ExtensionEngine Reviews
Write a ReviewPrototype-to-handoff process that our developers actually appreciated
Megan Foster / Head of Technology - Clearwater LogisticsJan 04, 2024
Project summary: Our internal engineering team had reached capacity and we needed a partner with complementary skills to help us deliver a critical platform upgrade on a tight deadline.
Our industry has specific compliance requirements that many generalist agencies struggle with. This team came with working knowledge of the relevant frameworks, asked pointed questions about our obligations, and built controls into the architecture rather than bolting them on at the end. Our compliance team reviewed the delivered system and had only minor observations, which is genuinely unusual for a first-pass review. That domain awareness saved us significant remediation cost.
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
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

Project summary: Our client portal was a reputational liability — we needed it to reflect the same standard of professionalism our lawyers delivered in person.
The engagement started with a discovery workshop that immediately signalled this team was different. They pushed back on two of our assumptions in the first session with evidence and a better alternative. That kind of intellectual honesty is rare and it set the tone for the whole project. Deliverables were consistently ahead of schedule, code reviews were taken seriously, and the final product is something we are proud to show enterprise clients during due diligence calls.
Domain knowledge that went beyond generic expertise into our specific industry, willingness to push back constructively, automated test coverage that gave us deployment confidence
Time zone difference required some adjustment to our internal communication habits but the team managed the overlap window efficiently and it never affected momentum
