Available to hire
I’m Marcelo Pagni, a self-taught IT professional with a long career spanning backend and frontend development, software operations, and information security. I started programming in QBasic on a CZ Spectrum back in the 80s at age eight, and since then I’ve built a broad skill set through hands-on work and a steady stream of courses. I enjoy solving problems with pragmatic, innovative approaches and I believe if something exists, we use it; if it doesn’t, we invent it.
I’ve served in both multinational and small companies, always focused on service and responsibility. My experience covers structured cabling, systems administration, security, and development, with a passion for delivering reliable software and secure infrastructure. I thrive in teams that value curiosity, learning, and practical impact.
