Systems and Computer Engineer from EIA University, based in Medellín, Colombia. I design multi-tenant SaaS backends, enterprise apps on Power Platform and AI agents that do real work — and I love taking apart how things work.
Outside work I reverse-engineer file formats and protocols, write native macOS apps and automate my home.
🟢 Open to freelance work: AI agents, SaaS backends, Power Platform apps, or any project that wants to change the world. Write to me in English or Spanish.
