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 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 is in response to Zama bounty Build a Confidential Benchmarking and Polling System Onchain using fhEVM.

• 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 supported by PSE Acceleration Program grant / Ethereum Foundation.

• In 2024 Q3, completed PSE Core Program to gain a deeper understanding on programmable cryptography. At the end of the program, delivered capstone project Number Guessing Game, a game that awards player making a guess closest to participants' mean, using zero-knowledge proof written with circom toolchain.
