IoT architecture that scaled from pilot to full fleet without a single redesign

Gustavo Ferreira / VP of Technology - Amazônia Digital Ltda
Verified
Feb 16, 2026

Project summary: Several years of incremental development had left us with a platform that was technically functional but strategically limiting. A structured rebuild was the agreed path forward.

What made the most difference in practice was the quality of the engineering judgment on this team. Not the ability to execute a specification — that is a baseline expectation. The ability to recognise when a specification was suboptimal, explain why, propose an alternative, and support the client in making a decision about it. That consultative dimension elevated the output beyond what the brief described and resulted in a product that is more fit for purpose than the one we had originally specified.

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.
Amazônia Digital Ltda is an established Human Resources organisation headquartered in São Paulo, Brazil. My role as VP of Technology 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?
Our platform had been maintained by a previous vendor for three years and the accumulated technical debt had reached a point where delivery velocity had dropped to a fraction of what it should have been. We needed fresh engineering expertise and a structured plan to address the underlying issues.
What services did the company provide for your project?
End-to-end IoT 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?
The quality of the questions they asked during the briefing process was the first indicator. Vendors who ask precise questions in the sales phase tend to apply the same rigour during delivery. That hypothesis proved accurate. The technical proposal was substantive, the team structure was senior throughout, and the pricing was transparent.
How clearly did the company understand your requirements and business goals?
Extremely well, in part because they had relevant Human Resources 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?
Outstanding. The discipline around asynchronous communication was particularly effective given the time zones involved between São Paulo, Brazil 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?
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?
We went live four months ago. User adoption exceeded the target we had set by 23 percent in the first month. Support ticket volume has dropped measurably. The features we had deferred because the previous architecture made them prohibitively expensive to build are now in development. The platform they built has opened our roadmap.
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?
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 Human Resources sector looking for IoT Development expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

Outstanding service and exceptional results

James Wilson / IT Director - Enterprise Systems

Project summary: The project demanded deep technical expertise and a thorough understanding of our business domain.

From the discovery workshop to the final handover, the experience was seamless. The team invested real effort in understanding our business goals before writing a single line of code, and that foundation paid dividends throughout. Every milestone was hit, every deliverable was polished, and the few issues that arose were resolved before we even had to ask. The solution has already delivered measurable ROI and we are planning our next engagement with them.

We are a IT Director-led organisation operating in the Legal Services sector. My role involves overseeing strategic technology decisions and vendor partnerships. We have been growing steadily and needed a trusted partner to help us scale our digital capabilities.
What specific problem or business challenge led you to hire this company?

What services did the company provide for your project?
They delivered a comprehensive Embedded Systems Development engagement covering requirements analysis, solution architecture, full-cycle development, QA testing, deployment, and post-launch support. The scope was well-defined and executed without scope creep.
Why did you choose this company over other providers you considered?
Their demonstrated expertise in Embedded Systems Development and a strong portfolio of Legal Services projects set them apart during our evaluation. The discovery call gave us confidence they truly understood our domain, not just the technology.
How clearly did the company understand your requirements and business goals?
Exceptionally well. They ran a structured discovery process, asked insightful questions, and produced a detailed requirements document that captured nuances we hadn't even articulated ourselves. That foundation made the entire project smoother.
How was your overall experience with their communication and project management?
Outstanding. We had a dedicated project manager, weekly status calls, a shared project board, and same-day responses to queries. There were no surprises — risks were flagged early and resolved before they became issues.
Did the company deliver the project on time and within your expected budget?
Yes, the project was delivered on the agreed date and within budget. Their estimates were realistic and they managed scope carefully, flagging any potential changes before they impacted the timeline or cost.
What tangible results or business impact have you seen since the project was completed?
Significant. Since go-live we have seen measurable improvements in operational efficiency, customer satisfaction scores have risen, and the solution has already paid back a substantial portion of the investment. The team built something we are genuinely proud of.
What did you like most about working with this company?
Their genuine investment in our success. They didn't just execute a spec — they brought ideas, challenged assumptions, and cared about the outcome as much as we did. The quality of the codebase and documentation also stood out.
Would you recommend this company to others, and would you work with them again?
Absolutely and without hesitation. We have already referred two colleagues, and we are actively scoping the next phase of work with them. They are our go-to partner for Embedded Systems Development projects going forward.
