ABOUT VLADYSLAV YUSIUK
Vladyslav Yusiuk is an applied cryptography engineer with a strong focus on zero-knowledge proofs, SNARK/STARK systems, and scalable blockchain infrastructure. He has practical experience working with advanced cryptographic tools and libraries such as Plonky2, Groth16, Circom, and Poseidon, and is proficient in Rust, Go, Solidity, and Circom DSL. His work spans zk-circuit engineering, cryptographic benchmarking, protocol optimization, and backend infrastructure. As part of his Master’s thesis at the University of Waterloo, Vladyslav developed a zk-SNARK SAT solver and a proof-generating co-processor targeting privacy-preserving L2 systems. Vladyslav is passionate about building verifiable, secure, and high-performance systems across decentralized architectures. He combines research-grade depth with hands-on implementation, delivering scalable cryptographic solutions in a rapidly evolving Web3 landscape.
