Lead Backend Engineer

I’m primarily a Backend Engineer and Blockchain expert with a strong focus on DeFi and open-source contributions. I’ve led cross-functional teams at Able Labs to create scalable backend solutions, while mentoring engineers to ensure high-quality results. At Curve Finance, I led QA for smart contracts, ensuring security and scalability across multiple blockchain networks, contributing to the protocol’s growth to nearly $25B in TVL. I’m passionate about improving blockchain technologies and have contributed to projects like vefunder/crvfunder, vyperlang/vyper, ApeWorX/ape, and eth-brownie/brownie, focusing on smart contract performance, cross-chain integration, and developer tools. With expertise in Solidity, Vyper, Python, Go, and blockchain protocols like Ethereum and zkSync, I bring a mix of technical skills and leadership to everything I do.
