About me

I'm a self-taught software developer: outside of work hours I keep building my own projects and exploring new technologies, because for me learning doesn't stop when a course or a contract ends.

My background combines development with critical systems support: I've provided L1/L2 IT support for clients like Santander Bank and Adidas, leading the resolution of P1/P2 incidents under strict SLA compliance, and as a Junior Software Developer I helped build DPTelemetry, a mobile app for motorsport fans.

I'm ambitious: I'm not just looking for a job, I'm looking for a team where I can grow fast and, over time, lead projects.

🧠 Self-Taught

Continuous learning on my own initiative, both at work and beyond.

🚀 Ambition & Leadership

Led the resolution of critical P1/P2 incidents under strict SLA.

🤖 Applied AI

Building efficient, scalable software for multiple environments. Clean architecture, microservices, and maintainable code.

🐳 Containers & Orchestration

Packaging applications with Docker and automating deployment through Docker Compose and clustered environments.

🛡️ Networking & Zero Trust

☁️ Self-Hosting & Cloud
