Custom API and backend development
We build the systems underneath — typed, tested APIs on Fastify and FastAPI, with encrypted per-tenant data and clean contracts, secure by default rather than secured later.
The backend is where security and scale are either designed in or bolted on. We design them in: encrypted per-customer configuration, access scoped from the start, and infrastructure that scales without a rewrite — the same substrate that runs under every Ekarche product.
The result is a service your own team can read, extend, and trust — with the contracts, tests, and documentation that let it outlive the engagement.
What we build
-
Typed, tested services
APIs on Fastify (Node) and FastAPI (Python) with strict typing and coverage built up alongside the code, so the thing that ships is the thing that was checked.
-
Secure and private by default
Encrypted per-tenant data, scoped access, and privacy designed in — the posture that lets a product credibly promise it never sells your data.
-
Scalable from day one
Stateless, idempotent, and coordinated so infrastructure scales up and out without code changes when the load arrives.
