Fullstack Developer

Montevideo, Uruguay

Juan Triunfo.

Building software with clean architecture, intuitive experiences, and attention to every detail.

About me

I enjoy turning complex problems into simple, reliable software. Whether designing system architecture or refining implementation details, I believe thoughtful engineering is what makes digital products stand the test of time.

My work is centered around building reliable systems, writing maintainable code, and creating products that are as enjoyable to use as they are to develop.

Outside of my daily work as a Backend Developer, I also teach programming, where I enjoy helping future developers build strong foundations.
