Full-stack developer with a strong backend foundation, based in Mendoza, Argentina. I build production SaaS products and scalable web applications with NestJS, React, Laravel, and Flutter.
About Me
I'm a full-stack developer who started with PHP and vanilla JavaScript, building REST APIs with JWT authentication and MVC architecture. Today I work with modern frameworks like NestJS, React, Laravel, and Flutter, building production products and scalable applications. I focus on clean architecture, well-documented APIs, and code that solves real business problems.
