Full-Stack Developer | Web & Apps | AI-Powered Development | Specializing in Cloud Computing

About me
The Developer
From codeto production,heading for the cloud.
I'm a self-taught full-stack developer: outside of work hours I keep building my own projects —from a home server running self-hosted services to AI assistants for real businesses— because for me learning doesn't stop when a course or a contract ends.
My background combines development with critical systems: I've provided L1/L2 IT support for clients like Santander Bank and Adidas, leading the resolution of P1/P2 incidents under strict SLAs, and as a Junior Software Developer I helped build DPTelemetry, a telemetry mobile app for motorsport fans.
I'm now specializing in Cloud Computing with Azure. I'm looking for a team where I can grow fast, contribute from day one and, over time, lead projects.
