The outcome we specified, delivered the way we needed it, by people we would hire again

Ji-Woo Park / VP of Engineering - Seoul Digital Corp
Verified
Jan 27, 2026

Project summary: The project had a board-facing delivery date tied to a strategic initiative. We needed a partner who would treat that date as their own, not ours.

Six months after go-live our platform is processing three times the transaction volume we specified in the original brief. The architecture choices made during discovery accommodated that growth without remediation work. That is the difference between a team that designs for what you tell them and a team that designs for what you are likely to need. We are in conversation about a Phase 2 engagement and I expect to be using this partnership for several years.

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

We underestimated the input required from our subject matter experts during the requirements phase. The team flagged this early but our resource planning did not fully reflect it — our responsibility, not theirs

Questions & Answers

Please describe your company, your role, and the industry you operate in.
I lead technology at Seoul Digital Corp, a growth-stage Food & Beverage business based in Seoul, South Korea. As VP of Engineering 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?
We had a defined product vision for our next phase of growth in the Food & Beverage market but lacked the engineering depth internally to execute it. The Industry-Specific Solutions 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?
End-to-end Industry-Specific Solutions 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?
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?
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. I had privately built a contingency expectation into my planning given the project complexity and the number of integrations involved. None of that contingency was needed. The delivery landed on the agreed date and the final invoice matched the approved budget to within a fraction of a percent. That outcome is rarer than the industry acknowledges.
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 Industry-Specific Solutions programme in the Food & Beverage space and will deliver against a serious brief, this is the team.

Observability stack that caught three production issues before any user reported them

Yuki Hashimoto / Head of Product Development - East Asia Commerce KK
Verified
Jan 11, 2026

Project summary: Rapid growth had created a skills gap on the platform engineering side of our business. We needed an experienced partner to close that gap while our internal team scaled, without compromising quality or timeline.

I came into this engagement as a sceptic. We had been through a failed implementation with a previous vendor and I had high standards for what evidence of competence looked like before I would trust a partner with our core systems. This team earned that trust progressively — through the quality of the discovery documentation, the rigour of the technical proposals, the consistency of the sprint deliveries, and ultimately the stability of the production system. I no longer lead with scepticism when recommending them.

PROS

Production system that has performed as specified since go-live without remediation work, documentation thorough enough to support internal maintenance, knowledge transfer that left our team genuinely capable

CONS

Their discovery process is more rigorous than we were accustomed to and required more preparation from our side than we had initially allocated — but the quality of what followed justified every hour of it

Questions & Answers

Please describe your company, your role, and the industry you operate in.
As Head of Product Development at East Asia Commerce KK I oversee technology investment and delivery across our Information Technology operations in Osaka, Japan. 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?
The immediate problem was that our DevOps Services 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 DevOps Services 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?
A trusted peer in the Information Technology sector had used them for a comparable DevOps Services engagement and their recommendation was unequivocal. Our own due diligence confirmed the pattern they described. The combination of domain knowledge, DevOps Services 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 Information Technology 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?
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?
Quantifying the impact precisely is complicated by other variables in our business, but the metrics we can attribute directly to the DevOps Services 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?
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 Information Technology sector looking for DevOps Services expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.
