What I'm looking for

I’m looking to build and harden secure smart contracts for DeFi/L2 systems—owning migrations, protocol architecture, and production reliability—while collaborating closely with product and engineering teams to deliver dependable releases.

I’m a Blockchain / Smart Contract Engineer with 6+ years of experience designing, testing, and deploying secure, production-ready Solidity smart contracts for staking, incentives, NFTs, and Web3 applications. I bring a security-first mindset and deep experience translating business requirements into reliable DeFi-grade implementations.

I’ve led V1→V2 protocol migrations end-to-end, coordinating smart contract upgrades and data transitions for staking platforms. I deliver Layer 2 compatible solutions using Optimism/Arbitrum-style architectures, and I support reliability through archive and non-validator node operations for HyperEVM.

My testing workflow is built around Foundry and Hardhat (unit tests, integration tests, and mainnet-fork testing), and I’ve shipped incentive mechanisms like POAP-based bonus and incentive logic integrated into staking ecosystems. Beyond Ethereum/L2, I’ve built with Go and the Cosmos SDK, and I’ve developed permissioned blockchain systems and chaincode with Hyperledger Fabric, including a high-scale voting application.
