20 years in hardware & IT support → now writing software that runs close to the metal.

👨‍💻 About Me

I'm a career-changer who spent two decades in consumer electronics and IT infrastructure before committing fully to software development. That background gives me something most junior devs don't have: a deep intuition for how hardware and software interact, and a professional mindset forged in real client-facing environments.

Since joining 42 Málaga — a rigorous, project-based engineering school with no lectures and no hand-holding — I've built everything from scratch: memory allocators, a Unix shell, an IPC messaging system, and a complete C++ OOP module series.

I write C and C++ the hard way: manual memory management, raw system calls, POSIX threads, no shortcuts.

🎯 Looking For

I'm actively looking for my first professional developer role. Here's what I'm targeting:

  • 🔧 Roles: Backend Developer · Systems Developer · Embedded Software · IT Support · DevOps/Infra Junior
