Q.01
What do you actually do?
I take Web3 product ideas and ship them as production software — smart contracts on EVM chains, React or Next.js frontends with wallet integration, and the off-chain infrastructure that ties it all together.

[03] About
“Crafting the Future of Web3.”
Q.02
Who do you work best with?
Founders launching a token or dApp who need one person to own contracts, frontend, and deployment. Teams that need a Solidity engineer who also ships polished UIs.
Q.03
What's your one rule?
Ship what was promised, on the timeline that was agreed. Security-first smart contracts, honest estimates, and no hero commits that wreck the next sprint.
Q.04
What are you working on right now?
Gas-optimized and security NFT minting flows, a DeFi staking dashboard on Base, and smart contract audits for a token launch.
