At Kleros, I built an idempotent, crash-resistant event-driven notifications and keeper platform that processes 8,000 blocks per hour and serves 800 users. I implemented 15 triggered actions and shipped GraphQL endpoints for account status and activity.
At Vitoshis, I engineered a Node.js backend to enforce game logic and prevent a client-side scoring exploit, and wrote and deployed an ERC-20 contract on Ethereum. At Cherry Byte Technologies, I improved the ndau block explorer’s load times by 90% and developed an NFT creation protocol on the Ripple Blockchain.
