Computer Engineer (Ingeniero en Informática) specialized in backend development and application architecture. My core stack is Python (FastAPI) and Java (Spring Boot), building high-performance REST APIs and systems designed to scale, with Angular, PostgreSQL and Docker for full-stack delivery.Before writing a single line of code, I invest in architecture design, data modeling and technical planning — quality software starts with a solid foundation. I run a test-first, milestone-based delivery process: every deliverable ships with an automated test suite, documentation, migrations and Docker deployment, plus a working demo at each milestone so you can verify progress before paying.Recent work: a multi-tenant SaaS platform built end to end (FastAPI, SQLAlchemy 2 async, PostgreSQL 16 with row-level security, Stripe billing, Celery/RabbitMQ workers, 690+ automated tests) and an Angular + FastAPI operations backoffice.Clear, fast written communication in English and Spanish, honest progress reports, and strict deadline compliance. You don't just get functional code — you get a documented, tested system your team can maintain without me.Computer Engineer (Ingeniero en Informática) specialized in backend development and application architecture.
