Luis L
About this gig
Need a fast, secure REST API or someone to fix bottlenecks in your existing backend?
I design, build, and debug production backend architectures using Node.js (Express/TypeScript) and Java (Spring Boot), backed by solid relational database design and Redis caching.
Services included:
- Custom RESTful APIs: Clean, modular endpoints built with Node.js/TypeScript or Java Spring Boot.
- Security and Auth: Stateless JWT authentication, role-based access control (RBAC), strict input validation, and secure password hashing.
- Database Engineering: Relational schema modeling, SQL query optimization, and migrations in PostgreSQL, MySQL, MariaDB, and Redis.
- Debugging and Refactoring: Resolving concurrency bugs, broken routes, or slow database queries.
Why work with me:
- Clean Architecture principles and structured JSON error handling.
- Ready-to-use API documentation (Postman or Swagger/OpenAPI) and optional Docker setup.
Message me before ordering to discuss your backend!

FAQ
Should I choose Node.js TypeScript or Java Spring Boot?
Node.js with TypeScript is ideal for fast SaaS MVPs and I/O-heavy APIs, while Java Spring Boot excels in strict enterprise backends. Message me and I will advise on the best fit.
Do you include API documentation for devs?
Yes. Every Standard and Premium API delivery includes a Postman collection or OpenAPI/Swagger specification so your frontend or mobile developers can connect quickly.
How do you handle authentication and API security?
I implement stateless JWT authentication, role-based access control (RBAC), strict input schema validation, and secure password hashing (BCrypt/Argon2).
