Backends built to run in production.

Node and Python services, clean REST and RPC APIs, and disciplined data access — all behind a gated QA wall that blocks stubs, secrets, and injection before anything ships.

Why it matters

The backend is where trust is won or lost.

Data isolation, auth, and correctness are invisible when they work and catastrophic when they don’t. We engineer them as first-class concerns.

A backend has to be correct, secure, and maintainable long after launch. We build services in Node and Python with clean, well-typed APIs and a disciplined data-access layer — every endpoint scoped to the authenticated user so tenants never see each other’s data. Nothing ships as a stub: an anti-stub guard rejects placeholder functions, TODOs, and mock data before delivery, and a security pass audits for hardcoded secrets, injection, and open CORS. This is the same discipline running the backends of all 18 of our live platforms.

Clean interfaces, isolated data.

We design REST and RPC APIs with clear contracts and a data-access layer where every query is scoped to the authenticated user — so a new tenant starts empty and never sees anyone else’s data.

  • Well-typed REST and RPC APIs with documented contracts
  • Per-user data isolation scoped at every endpoint
  • Postgres with disciplined migrations and query layers
  • Auth, rate limiting, and input validation as defaults

Production-complete or it doesn’t ship.

Every backend deliverable passes an anti-stub guard and a security audit before release. No TODOs, no pass-only functions, no hardcoded mock data — and the developer writes the tests, not an afterthought.

  • An anti-stub guard that blocks placeholder code pre-delivery
  • Unit and integration tests written as part of the deliverable
  • A security pass for secrets, injection, and open CORS
  • A ship / no-ship quality gate before any release
  • Observability wired in so production issues surface fast

FAQ

Questions we get asked

Node.js and Python are our primary backend runtimes, typically with TypeScript, FastAPI, or Express. We choose per project based on the workload and the team that will maintain it.
Every endpoint is scoped to the authenticated user, and a new account starts completely empty. There are no shared or global data files — per-tenant isolation is enforced at the data-access layer.
An anti-stub guard runs before delivery and rejects TODOs, pass-only functions, and mock data. A generation that fails the guard is retried, not shipped — so what you receive is production-complete.
Yes. A security audit checks for hardcoded secrets, injection risks, unauthenticated endpoints, and open CORS as part of the quality gate before release.
