NestJS Backend Developer
I design and build NestJS APIs with clear boundaries, validated data and production-minded error handling.
Reliable APIs
Validated requests, predictable responses and explicit error handling.
Security built in
Authentication, authorization and safely handled credentials.
Ready for production
Automated tests and Docker-based deployment workflows.
Scope of the work
A NestJS API organizes product rules into identifiable routes and services. Depending on the product, work can include input validation, error handling, authentication and communication with the database.
Clear module and responsibility boundaries help an API evolve without putting all its logic in controllers. Input and output contracts are made explicit to simplify front-end integration and help diagnose unexpected responses.
Tests can cover business rules and responses from the most important routes. Clear documentation of endpoints and expected errors makes front-end integration easier and supports handover to other people on the team. Those contracts also help prevent API changes from unexpectedly breaking consuming applications.
