40mExperience
Experience
61% firm-wide AI adoption. 11 internal apps shipped.
Every desk I've sat at taught the same lesson a different way: find the edge, then go build it.
I've led AI strategy inside a communications firm and now inside a medical device company, building the team and the systems from zero each time.
150mEntrepreneurship
Entrepreneurship
2 companies acquired. $400K+ revenue, 100,000+ users at Mocean.
It started small: flipping baseball cards, washing dishes, then reselling sneakers.
Five ventures between high school and college, from sneaker arbitrage to Mocean, a research platform that grew to 100,000+ users. Two were acquired. Each one is written up honestly, including what went wrong.
150mPortfolio
Portfolio
20+ products shipped. Every one opens as a live, clickable demo.
What that instinct ships now: real products, end to end.
The products I build and run now: Riptide Research, Galactic Signals, Sonar Media, Observly, BriefBridge, mTrain, and the Dog House band site. Each card says what it is and what it does, and opens a live demo you can click through yourself.
300mSkills
Skills
All those years of building, across markets and code, became a real toolkit.
AI engineering, full-stack development, markets and quant, data, product, and design. Not a keyword wall: these are the tools I ship with every day, from Next.js and Supabase to RAG pipelines and Claude.

Education
With the foundation underneath all of it.
University of Michigan, B.A. in Economics. I started at WashU St. Louis in entrepreneurship before transferring. Econ gave me the markets lens the rest of this site is built on.
900mInterests
Interests
And a life outside the work, though most of it circles back to it.
Music runs deepest: sax and piano first, then producing, now house sets behind the decks. I also shoot photo and video on a Sony A7 IV and DJI gear. The rest of the rotation: markets, sneakers, and whatever is new in tech.

If any of this resonates, let's build something.
Booking a time directly is the fastest path; LinkedIn and email work too. Always happy to talk AI, markets, or building.
