About Me

I’m a full-stack software and protocol engineer passionate about privacy, decentralization, and cryptographic innovation. With over two years of hands-on experience in zero-knowledge proof systems, blockchain protocol development, and end-to-end Web3 application design, I’ve worked across the entire stack—from frontend interfaces to smart contracts and ZK circuits. My focus is on building scalable, privacy-preserving systems such as stealth address protocols, on-chain mixers, and regulatory-compliant ZK infrastructure. I’ve contributed to multiple zk-SNARK and Circom-based projects, developed custom wallet SDKs, and participated in hackathons and research initiatives around digital identity, inheritance, and private DeFi. I thrive in environments where cryptography meets real-world usability—bringing together low-level ZK logic, smart contract automation, and intuitive UX into unified, secure experiences.
