I help protocols make on-chain code safe to run in production: security hardening, refactoring legacy programs, integration test infrastructure, and multisig-based contract administration. Anchor by default, Pinocchio when the compute budget matters.
Selected production work
- Maintained a vesting program holding $20M TVL
- IDO contracts handling $400K in sales and 2,000 participants per launch event
- NFT lending protocol — 8 custom programs integrating third-party DeFi infrastructure
- Audited and refactored a legacy Solana codebase, then built its integration test suite from scratch (contracts + off-chain)
Open source
- Pinocchio — Token-2022 extensions interface (#330, #333)
- LiteSVM test suite adopted in Turbin3 development (#6)
- Solana Kite — Rust ergonomics improvements (#2)
- Pinocchio Solveil — on-chain password manager, showcase program
