//Section 02 / About
Ibuildsystems,notdemos.
01
I started my first business at 15: a mobile detailing service I ran profitably for two years. Customers, pricing, scheduling, books. That operations instinct now drives everything I build in software.
Today I build AI-driven products for the parts of work that usually stay messy: finding vendors, organizing research, capturing notes, answering calls. Agents handle research and scaffolding. I focus on architecture, execution, and shipping.
