About

I'm a self-taught System Engineer who transformed from zero technical knowledge into the sole network architect for 50+ smart parking facilities nationwide. My unconventional path through Apprentice University's hands-on program taught me that the best solutions come from understanding both the technical details and business impact.

At ECO Parking Technologies, I've built the infrastructure that powers some of the nation's largest parking deployments, including a 693-sensor Las Vegas casino requiring custom 10G fiber solutions. When our legacy system threatened to limit our growth, I led the migration to a modern Cloudflare-based architecture, eliminating vendor lock-in and saving thousands monthly.

Beyond infrastructure, I'm a builder at heart. I've created production applications that our teams use daily—from a React-based cost calculator that speeds up sales quotes to a full-stack project tracker that integrates with legacy systems.

Currently pursuing my BSCNE degree to formalize my practical experience, I'm excited about the intersection of IoT, cloud infrastructure, and smart city technology.
