03 — About

Security first, always

I build production-grade smart contracts with a security-first mindset — threat modelling before the first line of Solidity, invariants and fuzzing before the first deployment.

Every contract I ship carries comprehensive test coverage in Foundry and verified deployments on-chain, with front-ends wired through Wagmi and Viem so the whole stack is auditable end to end.

I'm seeking a smart contract developer or security auditor role where I can bring production-ready Solidity expertise and audit-first rigour to serious on-chain teams.
