About Guillermo

Developing robust REST APIs, autonomous AI agents, and complete Full Stack applications that solve real business problems.
If you need to integrate artificial intelligence into your product, automate processes with Python, or build a solid backend with FastAPI or Spring Boot, I can help you. I also develop modern frontends with Angular and IoT systems with Arduino.
I differentiate myself by combining traditional backend experience with applied AI — a rare combination in today's market. All my projects are deployed in production and the code is clean, documented, and tested.
Available for short and long-term projects, remotely or in Madrid.
