At Kleros, I built a crash-resistant, event-driven notifications and keeper platform processing 8,000 blocks per hour for 800 users. I also shipped GraphQL account endpoints, implemented 15 triggered actions, and built end-to-end protocol integration tests that caught two critical vulnerabilities before release.
Previously at Vitoshis, I secured prize-based games by moving scoring logic into a Node.js backend with WebSocket state synchronization, while extending the React experience with new competitive games. I also wrote, tested, and deployed an Ethereum ERC-20 contract that generated more than 250 ETH in trades.
At Cherry Byte Technologies, I improved the ndau React block explorer's high-load page performance by 90%, built an NFT creation protocol on Ripple, and delivered an ERC-721 minting dapp that generated over 100 ETH.
