Backend Engineering
Secure, documented APIs and backends that power your web, mobile and partner integrations.
From $1,000.00
The app is slow, the data is inconsistent, and adding a feature means something else breaks. The front end gets the blame, but the real trouble is underneath: an ad-hoc backend with no tests, no docs, no rate limiting, and queries that fall over under load.
We build the backend properly: a secure, documented REST API with real auth, a clean PostgreSQL schema with migrations, background jobs, rate limiting, structured logging, and automated tests. It powers your web, mobile and partner integrations and it doesn't fall over when traffic arrives.
Node.js + Express 5, PostgreSQL 16 + Prisma migrations, Redis + BullMQ for jobs, Zod validation, OpenAPI docs, session/JWT/OAuth auth, Pino logging, Vitest + testcontainers, Docker deploy.
