About
I'm a full-stack developer, founder of SUDO and a network technician. I build web systems, mobile apps and WhatsApp AI agents end to end: requirements gathering with the client, data modeling, deployment and performance reporting.
I come from infrastructure: help desk, Linux servers, pfSense and structured cabling. That's why I understand a system from the cable up to the interface. I'm finishing my Computer Science degree (expected 2027) and studying Business Management, because good technology is the kind that produces business results.
