I ship the systems

Technical Program Manager in New York — I lead a 10-person cross-functional team and ship complex programs end to end, and I can read and write the code underneath them. Three products delivered: a live on-chain protocol, a cross-border fintech, and a payments marketplace.

BAGR

A music-industry marketplace where producers auction beats to artists — live bidding, licensing, escrowed payouts. On a ten-person team, I own the commerce and compliance backend.

Stripe payments with multi-state sales-tax compliance
Escrow-until-delivery: charge at close, license, then release payout
Authentication, identity verification, refunds, transactional email
The internal admin console and the team's go-live process
