Worked on the Lightprotocol/light-protocol repository to deliver formal verification for updated cryptographic circuits, focusing on enhancing the security and correctness of on-chain operations. Applied formal verification techniques using Lean and Go to refactor and extend verification logic around Merkle trees and hashing, improving both coverage and maintainability. This engineering effort strengthened the protocol’s cryptographic integrity, reducing the risk of defects and supporting safer deployments. The work aligned with security standards and emphasized robust, maintainable code. Demonstrated expertise in cryptography, formal verification, and zero-knowledge proofs, contributing to the reliability and trustworthiness of core protocol components without introducing new bugs.
