QA coverage that finally made Friday deployments feel like a professional activity

Aoife Brennan / VP of Product Engineering - Emerald Digital Ltd
Verified
Mar 23, 2026

Project summary: Our field service management system had not been updated significantly in six years. Rising technician count and increasing job complexity had exposed every one of its limitations.

The technical quality of the final deliverable is the easiest thing to point to. The automated test coverage is thorough, the deployment pipeline is reliable, the documentation is genuinely useful rather than ceremonially produced. But the metric I keep returning to is the number of post-launch conversations we have not had to have. No incident calls at two in the morning. No emergency patches. No retrospective discussions about what went wrong. The absence of those events is the evidence I would show to someone considering this vendor.

PROS

Collaborative culture that made the team feel like a genuine extension of our organisation, strong asynchronous communication across time zones, zero-drama handling of the inevitable mid-project changes

CONS

Time zone coordination required some deliberate overlap management from both sides in the first couple of sprints, after which we had an efficient async rhythm that worked for the whole project

Questions & Answers

Please describe your company, your role, and the industry you operate in.
As VP of Product Engineering at Emerald Digital Ltd I oversee technology investment and delivery across our Energy & Utilities operations in Dublin, UK. We are a commercially focused business and our technology choices are always evaluated in terms of their direct contribution to business outcomes rather than technical elegance alone.
What specific problem or business challenge led you to hire this company?
We had a defined product vision for our next phase of growth in the Energy & Utilities market but lacked the engineering depth internally to execute it. The Quality Assurance & Testing requirements in particular required specialist experience that we could not realistically recruit for on the timeline our business plan required.
What services did the company provide for your project?
Primarily Quality Assurance & Testing, with adjacent work in solution architecture and quality assurance. They were responsible for the full build from requirements through to go-live, including integration with four existing systems in our technology landscape. The breadth they covered without requiring additional vendors was commercially and logistically valuable.
Why did you choose this company over other providers you considered?
A trusted peer in the Energy & Utilities sector had used them for a comparable Quality Assurance & Testing engagement and their recommendation was unequivocal. Our own due diligence confirmed the pattern they described. The combination of domain knowledge, Quality Assurance & Testing depth, and demonstrated delivery discipline was the deciding factor.
How clearly did the company understand your requirements and business goals?
Comprehensively. The discovery phase they ran was more thorough than anything we had experienced with previous vendors. They challenged requirements that were vague or contradictory, proposed alternatives where our initial thinking was limiting, and produced a functional specification that our internal stakeholders agreed was the clearest articulation of the product they had seen written down.
How was your overall experience with their communication and project management?
Communication was proactive, timely, and appropriately calibrated. Technical updates for the engineering audience, executive summaries for the steering group, risk flags with proposed mitigations rather than just problem statements. The fortnightly sprint reviews gave our stakeholders visibility without requiring them to attend every working session.
Did the company deliver the project on time and within your expected budget?
Yes to both. There was a single sprint where a dependency on a third-party API introduced a one-week delay. The team identified it three weeks in advance, presented two mitigation options, and we agreed on an approach that recovered the schedule within the same sprint cycle. That level of foresight is what separates good project management from reactive problem management.
What tangible results or business impact have you seen since the project was completed?
The most direct measure is the performance of the system in production. In the five months since go-live we have had zero P1 incidents, our page performance scores have improved across every Core Web Vitals metric, and two enterprise clients who had cited our previous platform limitations during contract negotiations have since renewed without that objection arising.
What did you like most about working with this company?
Their instinct for keeping the business objective visible throughout technical decision-making. I have worked with technically excellent teams who lose the strategic thread as complexity increases. This team maintained a clear connection between every architectural choice and the outcome we had agreed to achieve. That orientation made the trade-off conversations significantly easier.
Would you recommend this company to others, and would you work with them again?
Unreservedly. We are in active scoping conversations for a second engagement and I expect this to develop into a multi-year partnership. For any organisation in the Energy & Utilities sector looking for Quality Assurance & Testing expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

Blockchain expertise that came with clear explanations, not just technical jargon

Eoghan Fitzgerald / VP of Engineering - Shannon Tech Solutions Ltd
Verified
Feb 20, 2026

Project summary: First notice of loss processing was taking three days on average. Market benchmarks were under four hours. Automation of the intake and triage workflow was the agreed priority.

The project brief was ambitious and we had received proposals ranging from two to five times our eventual budget from other vendors. This team came back with a proposal that was commercially realistic and technically credible — and then delivered against it. That alignment between proposal and outcome is not something I take for granted. I have been on the other side of it enough times to know it requires both honesty in the sales process and discipline in delivery. We experienced both.

PROS

Collaborative culture that made the team feel like a genuine extension of our organisation, strong asynchronous communication across time zones, zero-drama handling of the inevitable mid-project changes

CONS

The engagement was priced at the quality level rather than the budget level. We evaluated the alternatives and concluded that the delta was a reasonable premium for the reduction in delivery risk

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Shannon Tech Solutions Ltd is an established Insurance organisation headquartered in Dublin, Ireland. My role as VP of Engineering covers both strategic planning and operational technology delivery. We maintain high standards for our vendors because our clients hold us to high standards — a bar we expect our partners to meet.
What specific problem or business challenge led you to hire this company?
Regulatory requirements in our Insurance segment had changed and the compliance timeline was set by our regulator, not by us. The Blockchain Development changes required were significant enough to justify engaging a specialist partner rather than diverting our internal team from the product roadmap.
What services did the company provide for your project?
Primarily Blockchain Development, with adjacent work in solution architecture and quality assurance. They were responsible for the full build from requirements through to go-live, including integration with four existing systems in our technology landscape. The breadth they covered without requiring additional vendors was commercially and logistically valuable.
Why did you choose this company over other providers you considered?
A trusted peer in the Insurance sector had used them for a comparable Blockchain Development engagement and their recommendation was unequivocal. Our own due diligence confirmed the pattern they described. The combination of domain knowledge, Blockchain Development depth, and demonstrated delivery discipline was the deciding factor.
How clearly did the company understand your requirements and business goals?
Extremely well, in part because they had relevant Insurance experience that reduced the context-setting overhead significantly. They understood the domain vocabulary, asked the right questions, and translated business requirements into technical specifications with a fidelity that meant the development phase had very few clarification cycles.
How was your overall experience with their communication and project management?
The project management framework was the most structured I have experienced with an external vendor. Sprint planning was tight, acceptance criteria were specific, retrospectives were honest and acted on. The project manager treated the shared backlog as a live document and the risk register as an operational tool rather than a compliance artefact. I never had to ask for a status update.
Did the company deliver the project on time and within your expected budget?
On time and within the approved budget. The estimation accuracy was notable — they had broken the work down in sufficient detail during discovery that their forecast proved reliable throughout, rather than being a number that shifted with every change in scope. We received one change request and it was for scope we had introduced ourselves.
What tangible results or business impact have you seen since the project was completed?
The most direct measure is the performance of the system in production. In the five months since go-live we have had zero P1 incidents, our page performance scores have improved across every Core Web Vitals metric, and two enterprise clients who had cited our previous platform limitations during contract negotiations have since renewed without that objection arising.
What did you like most about working with this company?
The post-launch behaviour. Some vendors consider go-live to be the end of their professional obligation. This team treated it as the transition to a different kind of engagement. The hypercare period was substantive, the documentation was thorough and genuinely useful, and they checked in proactively at the thirty-day and ninety-day marks to review production metrics with us.
Would you recommend this company to others, and would you work with them again?
Unreservedly. We are in active scoping conversations for a second engagement and I expect this to develop into a multi-year partnership. For any organisation in the Insurance sector looking for Blockchain Development expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

ERP rollout that went live on the agreed date — we know how significant that is

Hyun-Su Lim / Director of Platform - Hanam Tech Solutions
Verified
Feb 07, 2026

Project summary: Our engineering capacity was committed to maintaining existing systems and could not absorb a net-new build of this complexity. An external partner with the right skills was the only viable option.

The integration layer was the part of the project I was most concerned about going in. Our system landscape is complex, several of the upstream APIs we relied on were poorly documented, and two third-party vendors had a history of unpredictable response times on integration questions. This team managed all of that. They documented what the upstream vendors could not, built resilience into the integration architecture where the upstream behaviour was unreliable, and delivered a solution that works as specified in production. I could not have asked for more.

Questions & Answers

Please describe your company, your role, and the industry you operate in.
I lead technology at Hanam Tech Solutions, a growth-stage Mining & Metals business based in Incheon, South Korea. As Director of Platform my remit spans product engineering, platform operations, and strategic vendor partnerships. We had reached an inflection point where our internal capacity was not sufficient to execute our roadmap at the pace our market required.
What specific problem or business challenge led you to hire this company?
The immediate problem was that our ERP Development capability had become the bottleneck limiting our ability to grow. Every feature request, every new client requirement, every internal initiative was delayed by a platform that had been extended beyond its original design. We needed a rebuild, not a patch.
What services did the company provide for your project?
End-to-end ERP Development delivery with particular depth in the integration and data migration components, which were the highest-risk elements of the programme. They supplemented this with a dedicated QA resource throughout development and a documented runbook for our operations team at handover.
Why did you choose this company over other providers you considered?
We ran a structured shortlisting process across five vendors. The technical evaluation eliminated two immediately. Of the remaining three, this team's proposal was differentiated by the specificity of their ERP Development approach and the evidence base they provided — reference projects in Mining & Metals contexts, not generic case studies. The reference calls confirmed a track record that the proposal had described accurately.
How clearly did the company understand your requirements and business goals?
Better than we managed ourselves going in. The workshops they facilitated surfaced assumptions we had not examined and exposed three requirements that were in direct conflict with each other. Resolving those before development began saved us what would certainly have been significant rework later in the project.
How was your overall experience with their communication and project management?
Outstanding. The discipline around asynchronous communication was particularly effective given the time zones involved between Incheon, South Korea and the delivery team. Written updates were specific and consistent, response times were same-day for anything that required a decision, and nothing fell through the cracks across a six-month engagement.
Did the company deliver the project on time and within your expected budget?
The project landed on time. The budget was managed within the agreed ceiling, which included one client-driven scope addition that was quoted fairly and handled without affecting the original delivery stream. The discipline around budget transparency throughout meant there was no surprise at invoice stage.
What tangible results or business impact have you seen since the project was completed?
The most direct measure is the performance of the system in production. In the five months since go-live we have had zero P1 incidents, our page performance scores have improved across every Core Web Vitals metric, and two enterprise clients who had cited our previous platform limitations during contract negotiations have since renewed without that objection arising.
What did you like most about working with this company?
The continuity of the team. The engineers who participated in the discovery sessions were the engineers who built the system. That consistency of institutional knowledge across a six-month project has a value that is difficult to quantify but easy to notice when it is absent. Every conversation built on the previous ones.
Would you recommend this company to others, and would you work with them again?
Yes. I would add the context that this is not the cheapest option in the market and they are selective about the engagements they take on. If your primary criterion is price, there are alternatives. If you want a technology partner who can be trusted with a complex ERP Development programme in the Mining & Metals space and will deliver against a serious brief, this is the team.

An honest assessment of where we were, followed by a credible plan for where we needed to go

The quality of documentation they produce means our team needed to set aside dedicated review time to do it justice — a minor scheduling point rather than a genuine criticism

Questions & Answers

Please describe your company, your role, and the industry you operate in.
As SVP of Engineering at Vertex Cloud Dynamics I oversee technology investment and delivery across our Events & Event Management operations in Austin, USA. We are a commercially focused business and our technology choices are always evaluated in terms of their direct contribution to business outcomes rather than technical elegance alone.
What specific problem or business challenge led you to hire this company?
A competitive threat had accelerated our roadmap. We had planned a significant IT Consulting investment for the following year. External pressure moved that timeline forward by six months and required us to find an external partner rather than attempting to build internally in the time available.
What services did the company provide for your project?
End-to-end IT Consulting delivery with particular depth in the integration and data migration components, which were the highest-risk elements of the programme. They supplemented this with a dedicated QA resource throughout development and a documented runbook for our operations team at handover.
Why did you choose this company over other providers you considered?
We had a failed engagement behind us and were more rigorous in our selection process as a result. We asked detailed questions about how they managed scope change, how they handled estimation, and how they communicated problems. The answers were specific, evidenced, and consistent across the team members we spoke to. That gave us confidence that the process was real rather than rehearsed.
How clearly did the company understand your requirements and business goals?
Comprehensively. The discovery phase they ran was more thorough than anything we had experienced with previous vendors. They challenged requirements that were vague or contradictory, proposed alternatives where our initial thinking was limiting, and produced a functional specification that our internal stakeholders agreed was the clearest articulation of the product they had seen written down.
How was your overall experience with their communication and project management?
Communication was proactive, timely, and appropriately calibrated. Technical updates for the engineering audience, executive summaries for the steering group, risk flags with proposed mitigations rather than just problem statements. The fortnightly sprint reviews gave our stakeholders visibility without requiring them to attend every working session.
Did the company deliver the project on time and within your expected budget?
On time and within the approved budget. The estimation accuracy was notable — they had broken the work down in sufficient detail during discovery that their forecast proved reliable throughout, rather than being a number that shifted with every change in scope. We received one change request and it was for scope we had introduced ourselves.
What tangible results or business impact have you seen since the project was completed?
Quantifying the impact precisely is complicated by other variables in our business, but the metrics we can attribute directly to the IT Consulting work are meaningful: session duration up, conversion rate up, error rate down, and our NPS for the digital touchpoint has improved by eleven points. Our account managers report that the new capability is coming up positively in client conversations.
What did you like most about working with this company?
The post-launch behaviour. Some vendors consider go-live to be the end of their professional obligation. This team treated it as the transition to a different kind of engagement. The hypercare period was substantive, the documentation was thorough and genuinely useful, and they checked in proactively at the thirty-day and ninety-day marks to review production metrics with us.
Would you recommend this company to others, and would you work with them again?
Yes, without reservation. I have already made two direct referrals within my Events & Event Management network — in both cases to peers facing IT Consulting challenges similar to ours. I gave those referrals with confidence because I knew the experience I described was reproducible, not the result of exceptional circumstances on our engagement.
