The backend your product runs on
APIs, logins, payments and data pipelines: the parts users never see but always feel. We build them properly and hand them over so your team isn't left guessing.
How we approach backend
We design and build the backend your product depends on: APIs and backend-for-frontend layers, authentication, payments, third-party integrations and data pipelines. This is the work users never see but always feel, through speed, reliability and the absence of surprises. We build in Node, Postgres, Supabase and Firebase, with clear contracts between services and code your team can read, test and change without guessing.
Delivery is automated and observable. We set up infrastructure as code and CI/CD so every merge can deploy, add monitoring and alerting that tells you something useful, and write runbooks so on-call is not a single person's memory. We have built ticketing and banking workloads under FCA and PCI constraints, where security, auditability and uptime are requirements rather than preferences. Whether you need a new API behind a mobile app, a safer payments flow, or a backend that is hard to change, we can review what you have, say what we would fix first, and hand everything over with documentation and a support window.
