I am passionate about Web3 and cryptographic development, with a current focus on programmable cryptography — including zero-knowledge proofs (zk), fully homomorphic encryption (FHE), and multi-party computation (MPC) — at both theoretical and practical levels. I am excited by the challenge of building services and applications that prioritize user privacy and employ robust, cryptographically secure architectures. I envision a future where technology empowers a freer, more democratic society as human civilization evolves.

• In 2025 Q3, participated in Ethereum Protcol Fellowship - Cohort 6, and integrated zkVM Brevis Pico into Ethereum Client Grandine to benchmark Ethereum state transition function.

  • Main Grandine integration PR.
  • Accompanied PRs on bls12_381 and sha256.

  Key skills: zkVM (Brevis Pico, RiscZero VM, Succinct SP1), Ethereum client (Grandine, Ream), Ethereum spec & testing process (consensus-specs, execution-specs, Kurtosis ethereum package), Rust

• In 2025 Q2, implemented Analytics dApp built on Zama fhEVM. This analytics dApp leverages fully homomorphic encryption (TFHE scheme), using fhEVM library, to encrypt respondent answers and perform aggregate analysis. The project was submitted to Zama Bounty Season 8 and won 2nd-place.

• In 2025 Q1, delivered Anonymous Multi-sig wallet with Semaphore Smart Account Modules. This project utilizes the Semaphore protocol to generate zero-knowledge proofs, enabling group members to endorse transactions while preserving anonymity. The initiative was granted by PSE Acceleration Program grant / Ethereum Foundation.
