Crafting robust, scalable web solutions.

GithubLinkedin

I am a full-stack developer focused on building scalable, maintainable backends and modern web interfaces. I work mainly with Node.js and Go on the server and React / Next.js on the front end, applying Clean Architecture principles. I use PostgreSQL and other SQL / NoSQL databases, and I containerize and deploy applications with Docker and AWS.

A RESTful API designed with Clean Architecture principles using Node.js and TypeScript. It features clear separation of concerns, dependency injection, repository patterns, role-based access control, extensible modules, and integrates with PostgreSQL. Ideal as boilerplate for scalable backend systems.
