I will build or fix your API
Christophe L.
About this gig
I'll build or fix production-ready Node.js/TypeScript APIs with clean architecture, validation, and automated tests.
I've shipped and operated cloud-native backends using TypeScript/Node.js + PostgreSQL (and also .NET in larger platforms), with strong focus on reliability and maintainability.
I can implement endpoints and business rules, design/adjust the data model + migrations, add auth (JWT/OIDC with providers like Keycloak/Auth0), integrate API gateways with rate limiting and request transformations, and provide OpenAPI/Swagger docs.
Delivery is a clean PR with tests (unit/integration), plus practical logging/monitoring hooks and a short handover so your team can extend it safely.

FAQ
Do you work with NestJS?
Yes, NestJS, Express, Fastify and similar stacks are all fine. Tell me what you use and I’ll adapt to your conventions.
Do you write tests?
Yes. I can add unit/integration tests (e.g., Jest) and basic API tests as part of the delivery, depending on the package you choose.
Can you add authentication?
Yes. I can implement JWT-based auth or integrate OIDC (e.g., Auth0/Keycloak) depending on your requirements.
Can you deploy it?
Yes, if you provide the target (AWS/Azure/Vercel/Docker/Kubernetes) and access. I can also containerize the service and add a simple CI workflow.
