Background

After working as a freelance engineer, I shifted my focus to independent research on cryptography and blockchain. I also run PQZK Labs (@pqzk-labs), an organization dedicated to repositories on Zero-Knowledge proofs and Post-Quantum Cryptography. Other projects and explorations will be published here on my personal repositories.
