Backend API Development
We build production-grade backend APIs with NestJS or Node.js. Authentication, authorization, database design, validation, error handling, and comprehensive documentation.
Building a backend from scratch takes weeks and it's easy to get architecture wrong. Bad API design haunts you for years with tech debt and scaling issues.
We build clean, well-structured APIs using NestJS — the most production-ready Node.js framework. Proper architecture from day one means less refactoring later.

Frequently Asked Questions
Why NestJS?
NestJS provides enterprise-grade architecture out of the box — dependency injection, modules, guards, interceptors. It's the most structured Node.js framework and scales well with team size.
REST or GraphQL?
REST for most projects — simpler, better caching, more tooling. GraphQL when you have complex data relationships and mobile clients that need flexible queries.
Do you include database design?
Yes. We design the Prisma schema with proper relations, indexes, and migrations. Database design is a core part of API development.
Can you build on top of an existing API?
Yes. We can extend, refactor, or optimize existing NestJS/Node.js APIs. We review the codebase first to understand the existing patterns.
