Backend APIs, typed end-to-end, paged for production.
APIs that survive contact with real traffic. Typed from the database row to the React component, paginated by default, idempotent where it matters, instrumented so you can see what they're doing in production. We build backends to be boring on purpose.
What we build
Types that cross the wire
Drizzle schemas generate the database types; tRPC routers expose them as typed RPC; the frontend client gets the same types without manual sync. Renaming a column in the database is a compile error in the React component.
Pagination as a primitive
Cursor-based pagination on every list endpoint by default. No `?page=N` math that breaks when data inserts mid-scroll. Infinite scroll, table pagination, and exports all run through the same primitive.
Idempotency on writes that matter
Payment-shaped operations (charges, sends, signups with side effects) accept an idempotency key and dedupe at the database level. Retries are safe by construction, not by hope.
Background jobs with retries
BullMQ on Redis for the queue, with explicit retry policies, backoff schedules, and dead-letter handling. Long-running work doesn't block requests; failed jobs surface in observability instead of disappearing.
Authentication and authorization, separated
Auth proves who; authz proves what they're allowed to do. Two layers, two test surfaces. The most common security bug in B2B SaaS is conflating them; we don't.
Observability that survives production
Structured logs at every API boundary, traces across the request → job → DB → external API chain, and dashboards you can actually read at 2am. We instrument what we ship; you see what's happening.
Where this fits
You're past the prototype API and need it to handle real traffic without rewriting it.
Your team is shipping features faster than the API contract can keep up with the frontend, and types are slipping.
Background jobs are silently failing in production and you don't know which ones until a user complains.
