About

Founder of BUILD GEEKS inc. I build web services, iOS apps, and AI products — bridging the gap between technology and business. My background is in SRE and cloud infrastructure, and I'm currently hands-on with AI, Agents, and MCP tooling. I also train Brazilian Jiu-Jitsu and built BJJ Techniques to help practitioners systematize their learning.
