Work

At Fanatics Markets and Barstool Sportsbook I led engineering inside large, regulated businesses. I built Cigarista and Humm myself, from the first line of code to the support inbox. Below them, smaller tools I made because I wanted them to exist.

VP, Head of Engineering, Fanatics Markets · July 2025 to July 2026

Fanatics Markets

I led engineering for Fanatics Markets, a prediction market regulated by the CFTC rather than by state gaming commissions. It launched in December 2025, the first from a major US sportsbook operator, and reached 24 states in three days, including California, Texas and Florida.

Barstool Sportsbook

At Penn Interactive I built the engineering organization behind Barstool Sportsbook, from the first hire to 300 engineers, while we launched a real-money product in one regulated state after another.

Humm

Tap once and talk. Humm transcribes the note, files it, and reads your day back to you the next morning. I designed, built and run it alone, from the Watch app to the backend to the pricing.

tracon

Air traffic control for parallel Claude Code subagents. A live terminal and browser view that spots stuck, blocked and drifting agents, and two agents editing the same file before you merge. Read-only and local.

Sitch

Evernote discontinued Skitch for Windows in 2016, and hasn’t updated the Mac version since 2020. Sitch brings back the workflow on both: one hotkey to capture, the tapered arrow to annotate, and nothing leaves your computer.
