I make things people want.
Engineer with a founder's habits. I find the problem, talk to the people who have it, and ship until it works.
Problems I take from zero to one.
Money that moves
Getting money from where it is to where people need it: card loads, swap routing, payouts, cross-chain USDC. Systems I built carry $10M+ in card volume.
Proof: CCTP BridgeAI that decides
AI people can trust in production. Structured model decisions handle routing, scoped edits, and fallbacks, so the model only runs when it should.
Proof: HyperDraftWallets and chains
The hard parts of crypto, invisible to the user: keys, signing, simulation, and every chain they touch, from EVM to Solana to Stellar.
Proof: How a signature signsThe whole product
No PM, no designer, no handoffs. I talk to users, pick what matters, design it, build it, ship it, and own what happens next.

Do the thing.
- Preparing to do the thing isn't doing the thing.
- Scheduling time to do the thing isn't doing the thing.
- Making a to-do list for the thing isn't doing the thing.
- Telling people you're going to do the thing isn't doing the thing.
- Hating on yourself for not doing the thing isn't doing the thing.
- Hating on people who have done the thing isn't doing the thing.
- Fantasizing about the adoration you will get once you do the thing isn't doing the thing.
- Reading about how to do the thing isn't doing the thing.
- Reading about how other people did the thing isn't doing the thing.
The only thing that is doing the thing is doing the thing.
Heard it from @ralphhojr. Building by it.
