    Who our full-stack development is for

    Our full-stack development service is for CTOs and founders who need a complete product built, or an existing one taken over, by people who understand every layer. That might be a new platform, a customer portal, an internal tool that the business now depends on, or a codebase another team left half-finished.

    It is part of our software development practice and is delivered by senior engineers only, each with 25+ years of engineering experience. The same engineers design the database, build the API and ship the interface, so decisions in one layer aren't made in ignorance of the others.

    How we build

    We are stack-agnostic, but our most common choices are TypeScript, React and Next.js on the front end, Node.js or Python on the back end, and PostgreSQL for data, deployed on AWS or Google Cloud with Terraform and automated CI/CD. We choose based on what your team can maintain after we leave.

    We start with the data model and the riskiest parts of the system, because those are the hardest to change later. Features ship in small increments behind automated tests, and every environment can be rebuilt from code. Performance, security and accessibility are part of the definition of done, not a later phase.

    When we take over an existing codebase, including one generated with AI coding tools, we begin with a Code Audit and stabilise before adding features. We tell you plainly whether refactoring or rebuilding is the better route.

    Relevant work

    We built the entire online gaming platform for Full Color Games, letting players worldwide play their '21 or Nothing' card game. We built and optimised Mozilla Foundation's global fundraising systems, and built CliqScale.R, a cloud CFD simulation platform that lets scientists run OpenFOAM reactor scale-up simulations. We also took over and continue to develop the Know Your Lemons health app and website.

    How an engagement runs

    We start with paid scoping: an Architecture Assessment for a new build or a Code Audit for an existing codebase. You get a written plan and a realistic time and cost range before committing to delivery.

    Work is billed weekly on actual hours, code lives in your Git organisation from day one, and every project ends with documentation, a recorded walkthrough and 30 days of post-handover support. If you want continued development, we can move to team extension or a managed service.
