Super Cat Developer

I am a security-focused Ethereum smart contract engineer specializing in Solidity, with a proven track record of designing, shipping, and securing production-grade DeFi protocols. I have led the end-to-end development of complex systems including automated market maker (AMM) DEX implementations and yield aggregation vaults, emphasizing robust security architectures—such as reentrancy protection, role-based access control (RBAC), and time-locked privileged operations—along with high test coverage and gas-optimized contract design.

I am also experienced in conducting smart contract security audits using both automated tooling (e.g., Slither) and manual code review, with a clear focus on preventing critical risks like fund loss and privilege escalation. I thrive in environments that prioritize secure, efficient, and scalable blockchain infrastructure.

I am currently looking for a senior or lead smart contract engineer role in a forward-thinking DeFi/Web3 team where I can contribute to architecting secure, user-focused, and innovative protocols. I am particularly interested in teams that value rigorous engineering practices, security-first development, and open collaboration.
