About this gig

Are you building a complex application and need a backend that is secure, scalable, and easy to maintain?


I am a specialized backend developer with deep expertise in Node.js (NestJS) and PostgreSQL. I don't just write code; I architect systems. Using Clean Architecture and the CQRS (Command Query Responsibility Segregation) pattern, I deliver enterprise-grade RESTful APIs that are built to handle growth and high performance.


What You Will Get:


Robust API Development: Custom NestJS microservices or monoliths.

Advanced Patterns: Implementation of Clean Architecture, DDD, and CQRS.

Database Management: Optimized PostgreSQL schemas using TypeORM.

Security: JWT Authentication, OAuth, and Role-Based Access Control (RBAC).

Easy Integration: Fully documented APIs with Swagger/OpenAPI.

Quality Code: 100% TypeScript with strict typing and modular structure.


Why Choose Me?

Architecture-First Approach: I build software that is easy to test and extend.

Performance Focused: Efficient queries and optimized logic.

Production-Ready: Clean, bug-free, and deployment-ready code.
