Selected work
We publish work we can walk you through line by line. Each case study shows how the system was built (the architecture, the trade-offs, the safeguards), not just how it looks.

The standard
Whether it is a focused build or an ongoing retainer, these are not extras on a quote. They are how we work.
One typed contract between every app and the API, checked in CI, so the two can never quietly drift apart.
Automated suites on every change, with dedicated checks for the failures users notice before you do.
Metrics, alerting, and post-deploy checks go live with the product, not after the first incident.
Minimal data collection and verified erasure, tested automatically so a missed table fails the build.
Architecture decision records and runbooks written as we go, not reconstructed at handover.
Your repositories, your infrastructure, your accounts. No lock-in, no licence to keep paying us.
Tell us what you're building. We'll tell you if we're the right fit.
