01 Professional Summary

I build AI tools that real teams use every day, not demos. At GEMMACON North America, an automotive software consultancy, I find the slow, manual parts of how we run the business and replace them with software I write and ship myself, including agentic research pipelines, document automation, and containerized Python services. I start by sitting with the people doing the work to pin down what they actually need, then I build it so they can't easily get it wrong. Before that I spent a decade on connected-vehicle software at Toyota, Mercedes-Benz R&D, Hyundai, and PACCAR, and I still work as the technical liaison on our OEM programs.

Founder · kytimes.ai

I built, launched, and run a live product end to end: user accounts with Google and Apple sign-in, Stripe payments, weekly automated rankings, and a registered LLC behind it. The product itself is a joke bestseller list where the spots are openly bought.

Designed, built, and launched a production SaaS end-to-end — weekly-updated, genre-specific bestseller lists with bid-based placement, week-by-week archives, and social sharing.
Implemented full user management with Google and Apple OAuth — account creation, sessions, and profile flows.
Integrated Stripe for payment processing of ranked placements — checkout, billing, and webhook-driven fulfillment.
Formed a registered LLC and operate the product as a real business — legal disclaimers, analytics, and affiliate monetization.

A scroll-driven companion resume — the career drawn as a path across the US, with each role held in view as the map travels.

Built the experience section as a scroll-driven US map that zooms from city to city, draws the arc between jobs, and holds the role on screen at each stop.
Designed the page in Claude Design and implemented it in Cursor as a static site — no framework and no build step.
Shipped a layout that keeps the map, the rail, and the role card readable on a phone and on a wide desktop.
