Building secure, production-ready Web3 systems — smart contracts, cross-chain infrastructure, and full-stack dApps where security, decentralization, and usability intersect.
// 01 — about
Who I Am
I'm a Blockchain Engineer focused on building secure and scalable Web3 infrastructure. My work spans smart contract development, cross-chain communication, and distributed backend systems powering real on-chain applications.
Currently working at SentinelAI, where I develop security-focused smart contract systems and integrate Chainlink Functions, Automation and CCIP to deliver cross-chain threat intelligence pipelines.
Previously at Merkle Labs, I helped build gamified blockchain ecosystems including staking, reward engines and asset verification modules, improving engagement by 30%.
