At Backshire Platinum – G-Nation, I designed and deployed a five-contract payment infrastructure to Base mainnet. I took the project from a client brief through implementation and deployment, with a 26/26 passing end-to-end suite before mainnet launch.
I also led the Hardhat 3 migration, built a missing runtime module, and recovered a partial deployment to unblock rollout. The contracts shipped behind a 2-of-3 Gnosis Safe multisig and were verified on Sourcify.
At Ackee Blockchain, I reviewed Solidity and Solana codebases for security issues, writing tests and proof-of-concepts to confirm findings. At Guild Audit, I audited client smart contracts for access-control, accounting, and economic vulnerabilities and wrote remediation guidance.
My backend work includes a Go and PostgreSQL double-entry ledger served over REST and gRPC, with idempotent requests and row locks to prevent overdrafts under concurrency. In security research, I reported a solo High-severity finding for Crestal Network on Sherlock and have worked on ERC-4626 vault security.
