At VISEO, I implemented sanctions enforcement for the stablecoin of Anchorpoint, Hong Kong's first licensed stablecoin issuance provider. I also designed permissioned access contracts and an on-chain rate-limiting module, and wrote test suites that reached 90% coverage across 50+ smart contracts.
At Kingdomly, I built and scaled an NFT launchpad, marketplace, bridge, and staking ecosystem that supported 7K+ NFT projects and 3K+ contracts deployed. I started as the sole full-stack engineer, grew the team to 13 developers, and stayed hands-on from the Next.js frontend to Solidity contracts.
