About

My passion is building amazing teams that build just as amazing digital products. My background in software engineering started in web based backend APIs and then later expanded to web frontend expertise and systems architecture.
Later, I found that building teams and leadership was even more fun and challenging, but also let me scale up my ability to impact the product and the business.
Outside of work, I play electric guitar through a mix of new and old effects pedals, plus modeling and capture gear. I also build and mod mechanical keyboards, cook, and listen to a lot of Japanese rock and pop.
Now
Updated November 2026
- Between roles and looking for my next one.
- Experimenting with agentic AI, including a self-hosted Rakazo setup (a private, local Grokbot) to try AI as more of a personal assistant.
- Writing my own agent skills, and trying skills from Matt Pocock and poteto for a better agentic workflow.
- Working on Code Review Bench, looking for better ways to do agentic code review.
Experience
Startup engineering leader. I build engineering organizations, with product and design alongside, and ship the product while doing it. CTO or VP at four companies over the last eight years. I still architect and code, these days more with AI agents. Mostly e-commerce and omnichannel retail, more recently health and wellness.
