The problem

Students at UMSA's Faculty of Humanities had no central place to share study material.

01 / Plataforma Académica

The build

A sharing platform where students upload course material, comment and vote. Weekly and global leaderboards surface the best contributors. Reported content routes to a moderation queue with reviewer roles. Google OAuth2 — no passwords stored. Spring Boot REST API + Vue.

The result

My undergraduate thesis — deployed to production on the faculty's intranet, where students still use it.

GET /about

About me

Hi! I'm a backend developer based in La Paz, Bolivia.

I work at Banco Bisa, building backend services and internal applications — .NET and Java on the server, Angular on the front end, Oracle and SQL Server underneath.

Right now I'm focused on Go. I'm building REST APIs in my free time, applying hexagonal architecture and DDD, and studying how the language works under the hood — concurrency, internals, the parts most people skip. It's where I want to take my career.
