Write a ReviewData engineering quality that will support our growth for years without a rebuild
Hyun-Su Lim / Director of Platform - Hanam Tech SolutionsMay 29, 2026
Project summary: Our actuarial models had outgrown the reporting infrastructure feeding them. Data latency was introducing risk into pricing decisions that the business had decided it could no longer accept.
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.
Deep domain knowledge that reduced the discovery overhead significantly, proactive risk identification before issues became incidents, delivery cadence that our stakeholders found reassuring
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
Infrastructure-as-code that our SRE team treats as a reference example
Lars Pfeiffer / VP of Technology - NordTech Logistik GmbHMay 05, 2026
Project summary: A content deal had given us the rights to a major catalogue but our delivery infrastructure could not stream it reliably at scale. We needed a cloud-native video platform in under six months.
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.
Delivery timeline that proved achievable rather than optimistic, estimation accuracy that reflected real analysis rather than competitive bidding, scope discipline that prevented the feature creep we had experienced before
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
Performance testing that identified a latency issue three weeks before our biggest traffic event
Lars Pfeiffer / VP of Technology - NordTech Logistik GmbHApr 06, 2026
Project summary: Our connected vehicle platform needed to handle telemetry data from an expanding EV fleet while supporting over-the-air update orchestration. No off-the-shelf platform handled both requirements well.
We had worked with three agencies before this engagement. The comparison is not flattering to the others. What distinguished this team was a systematic approach to understanding the problem before proposing a solution — something that sounds obvious and is practiced far less often than it should be. The delivery phase ran to schedule, the codebase is clean enough that our internal engineers made positive comments during handover review, and we have not logged a critical incident in five months of live operation. We intend to use them for our next phase of work.
Architectural decisions designed for longevity rather than just the current brief, thorough automated test coverage, post-launch stability that validated every technical choice made during discovery
Their insistence on a detailed functional specification before development began felt like friction at the time. In retrospect, it was the reason the development phase ran without the ambiguity that has derailed similar projects for us previously
Questions & Answers
Robust, maintainable software our own engineers are proud to work with
Sinead Gallagher / Director of Engineering - Celtic Digital LtdFeb 02, 2026
Project summary: We had a clear product vision but lacked the engineering capacity internally to execute it within the window our market opportunity required.
Our previous agency had given us a platform that worked well enough to demo and fell apart under real load. This team came in, diagnosed the root causes accurately, and rebuilt the critical components without disrupting the live service. The performance improvements were immediate and measurable — page load times dropped by 60 percent, error rates dropped to near zero, and our support team has far fewer incidents to deal with. The contrast with our previous experience could not have been sharper.
Engineering quality that our internal team can maintain without calling the vendor, thorough documentation, proactive risk identification throughout the project
The volume of quality documentation they produced was genuinely impressive but also meant our team needed dedicated time to review it properly — a minor process point, not a complaint
Questions & Answers
A studio team who played the game obsessively and built it accordingly
Gustavo Ferreira / VP of Technology - Amazônia Digital LtdaJan 19, 2026
Project summary: A content deal had given us the rights to a major catalogue but our delivery infrastructure could not stream it reliably at scale. We needed a cloud-native video platform in under six months.
The thing that retrospectively seems most significant is how little drama there was. Complex technology projects tend to accumulate incidents, escalations, and tense conversations. This one did not. Problems were surfaced before they became incidents. Scope changes were handled with process rather than conflict. Risks were managed rather than avoided. That level of maturity is rare in my experience and it made the delivery feel almost effortless from our side, which I know it was not from theirs.

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
Infrastructure automation that freed our developers to focus on features again
Courtney Walsh / Director of eCommerce - Summit Retail GroupNov 06, 2024
Project summary: Document review and contract lifecycle management were consuming a disproportionate amount of fee-earner time that should have been spent on higher-value advisory work.
Project governance was one of the things that impressed me most. We had a dedicated project manager who ran tight fortnightly sprints with clear acceptance criteria, a shared backlog that gave us full visibility at all times, and a change request process that was fair and transparent. Nothing slipped through the cracks, no bill shock at the end, and the final delivery matched the original scope document almost perfectly. In my experience that kind of discipline is genuinely uncommon.

Questions & Answers
Smart facility solution that paid for itself inside the first quarter
Faisal Al-Ghamdi / Chief Digital Officer - Riyadh Tech VenturesDec 04, 2022
Project summary: Clinical trial data management was scattered across sites and formats and we needed a unified platform that could satisfy both our data science team and our regulatory affairs function.
Our previous agency had given us a platform that worked well enough to demo and fell apart under real load. This team came in, diagnosed the root causes accurately, and rebuilt the critical components without disrupting the live service. The performance improvements were immediate and measurable — page load times dropped by 60 percent, error rates dropped to near zero, and our support team has far fewer incidents to deal with. The contrast with our previous experience could not have been sharper.
Consistent delivery against milestones, code quality that passed our internal review without major findings, post-launch support that felt like a partnership not a ticket queue
Time zone difference required some adjustment to our internal communication habits but the team managed the overlap window efficiently and it never affected momentum
Questions & Answers
Virtual showroom that our sales team now uses every single day
Rohan Malhotra / Co-Founder & CTO - Crescendo Tech Pvt LtdJun 28, 2022
Project summary: Our growth into new markets required a multi-currency, multi-language commerce platform that our previous vendor had promised but never delivered.
I am a demanding client. I have a technical background, I review code, and I have high standards for documentation and testing. This team met all of those expectations without ever seeming defensive about scrutiny. Peer code reviews were welcomed, unit test coverage was genuine rather than performative, and the API documentation was thorough enough that our own developers integrated against it without a single clarification call. That level of craft is what I look for and rarely find.
