I'm a Full-Stack Developer with 5+ years of experience building production web applications. Currently at a startup in Lima where I've worked across the full stack — from NestJS microservices and real-time WebSocket systems to React/Next.js frontends, serving up to 5,000 concurrent users.

Some things I've built: a digital wallet ecosystem (3 frontends + 3 microservices), a tournament platform with live leaderboards, a multi-platform soccer analytics app with Redis-optimized queries, and CMS-driven marketing pages with SSR. I've also built an Android overlay app for Japanese manga translation using Google ML Kit OCR and the Gemini API — more of a personal project, but it shows I can work outside the browser too.

I have a B.Sc. in Informatics Engineering from the Pontificia Universidad Católica del Perú.

Looking for a remote full-stack or backend-leaning role at a product company. Open to async-first teams across any timezone. Happy to do a trial project.
