I write smart contracts and build the applications around them.

On-chain: Solidity contracts developed and tested with Foundry — ERC-20 tokens, escrow, multi-signature vaults, token sales, and staking contracts with reward accumulators. I write full test suites (my portfolio repo has 90 passing tests across four contracts), use audited OpenZeppelin components where they fit, and deploy and verify on testnet. I also build attack demos like reentrancy to check my own contracts hold up.

Off-chain: wallet authentication and access control (Metamask, WalletConnect), reading and displaying on-chain data through RPC providers, transaction handling with clear states and error feedback, and dashboards that make on-chain activity readable.

I've also built a cryptocurrency exchange with order book management and wallet integration, and a crypto analytics platform with real-time market data pipelines and Metamask-gated access.

Because I'm full-stack with 9+ years behind me, I can take a project from contract to deployed product rather than handing off halfway.
