We assigned two full-stack engineers and a solutions architect, both with experience of AWS and developing greenfield solutions, to oversee the end-to-end development process.

A key challenge was the requirement to maintain the same features, or parity, to support ongoing user adoption. As a black box system, while we knew the inputs and outputs, the internal workings were unknown and required us to reverse engineer the solution.

Doza assisted the Client on early user engagement with local authorities to ensure the technical feasibility of any proposed features to address current pain points and meet anticipated future needs.

We built a modern cloud native solution following GDS practices:

• Modern, serverless cloud services were selected for security, performance and cost efficiency benefits, as well as supporting the existing AWS skill sets and tools in place
• The tech stack supports scalability and future demand, allowing new features to be added and work effectively, and quicker development and fixing of issues.

Our iterative approach to solutions architecture delivered better, faster feedback loops (a client requirement).

Working as part of a rainbow team, we supported the upskilling of engineers on the team, including an apprentice. We worked with the Client on running stand-ups and retros, along with encouraging regular knowledge sharing sessions. Every two weeks we completed show and tells and weekly we presented progress and dependencies.

After the product go-live, we continue to support the team on feature development and bug fixes.
