I build backend and blockchain systems
I write here about the engineering behind them: cross-chain settlement, indexers, SDKs, smart contracts, and the AI harness I build to do the work.
Shipped
LI.FI Solver
The engine that fills cross-chain intents. I took it from an early draft to production, and it has moved past a million dollars.
Domain Names Marketplace
A domain-names marketplace on Seaport Protocol, from research through the backend and smart contracts.
ENS / UNS Indexer
An indexer over every ENS name ever registered, millions of them, kept correct with an eventual-consistency design.
Key Storage & Signing
Keeping Ethereum private keys in production without leaking them or slowing the service down. Vault-backed signing at DreamTeam, and a latency-sensitive version at Unstoppable.
Domain Resolution SDKs
Open-source libraries, in several languages, that resolve a blockchain domain to the address behind it.
Domains CLI + Go SDK
A CLI and a Go library for resolving blockchain domains, both written from scratch so a lookup is one command.
Wallet & Browser Integrations
Getting Brave, Blockchain.com, Alchemy, and Trust Wallet to resolve blockchain domains, with the work pushed down to about one line.
Trickle
On-chain hourly-rate contracts between parties, paid in any ERC-20 or stablecoin. It won the ENS prize at ETHCapeTown.
