Blockchain and cryptography researcher at Rango Exchange, author of three Ethereum standards and builder of a live zero-knowledge privacy protocol.

Turkey
Message

At Rango Exchange, I authored more than 30 integration and protocol research reports that informed co-founder decisions, and designed the company’s on-chain analytics dashboards and SQL queries. I also wrote technical articles and delivered an internal cryptography course.

I founded and built PolyShield, a zero-knowledge privacy vault for Polymarket that is live on Polygon mainnet. I designed its Circom/Groth16 circuits and Solidity vault, with client-side proof generation in the frontend.

I’ve authored three Ethereum standards and published research on cryptographic hashing and the quantum soundness of grinding in hash-based SNARKs. My open-source contributions span formally verified cryptography, Ethereum’s post-quantum consensus client, Zcash, and other cryptography projects.
