CTO at YARCONE building driver apps and multi-agent workflows that take AI coding agents from ticket to merged PR.

At YARCONE, I architected and built an iOS and Android driver app from scratch to replace spreadsheet-run deliveries. I also created a multi-agent orchestration system that takes AI coding agents from ticket to merged PR.

At VIONLABS, I hired and led four engineers to ship a greenfield enterprise portal unifying company data sources. I designed data-sync services that brought 1.5 million titles into one catalog, searchable in milliseconds.

At COLLECT.AI, I designed a type-safe form generator powering 25 forms and optimized state with RTK Query, cutting more than 2,500 lines of code. At NET2PHONE, I built a React and TypeScript WebRTC dialer for a UCaaS platform serving more than 200,000 business customers.

Through CLOSER, I reduced community setup from a day of manual work to 10 minutes with resumable, automated provisioning, and developed an MCP server exposing tRPC routers as OAuth-protected, read-only tools for Claude Code. I’m also the sole engineer and co-founder of WHOCARDS, where I built a custom e-commerce platform with integrated fulfillment and a 14-language iOS app.
