Custom applications, built to last
Purpose-built applications that are cheap to run and built to last.
Teams that need a bespoke tool — internal or client-facing — and don't want to pay for idle capacity or rebuild it in two years.
Yours to keep
Deployed to your AWS account, with the source code, the data, and the infrastructure-as-code all in your name. No proprietary platform, no per-seat lock-in — a documented handover so your team can take it in-house whenever you want.
Product & UX
Flows and information hierarchy designed for the people who will use this daily, not a generic CRUD scaffold.
Data modelling
Schema and access patterns agreed up front so the database never becomes the bottleneck.
Auth & access control
Role-gated access with Cognito — secure by default, extensible by design.
Integrations
APIs, webhooks, and third-party services wired with typed contracts that don't drift.
Serverless runtime
Lambda-based backend scales to zero between uses and to the spike on demand — lower long-term running cost than always-on infrastructure.
Architecture & planning
Data model, system boundaries, and event flow agreed on paper before a line of code is written.
Product & UX
Flows, hierarchy, and interaction patterns designed for the people who will actually use it.
Build
Production-grade implementation — typed end to end, deployed from day one.
SEO
Structure, speed, and copy aligned so search engines understand exactly what you offer.
Performance & optimisation
Load budgets set up front; Core Web Vitals and runtime cost tracked continuously.
Accessibility
Keyboard navigation, screen-reader semantics, and reduced-motion support — baseline, not a checklist.
