I am an AI-native Full-Stack Engineer who takes products from 0 to 1 — React / Next.js front ends, NestJS / Golang back ends, and storage layers like PostgreSQL, Redis, and ClickHouse. I enjoy owning complex systems end to end: shipping them to production, tuning latency and throughput, and debugging across the application, infrastructure, and protocol layers. Lately I've been exploring harness engineering and AI safety.

• Full-Stack (DeFi): Solely owned a Next.js frontend and backend services on Sui — re-architected PostgreSQL indexing and Redis caching to eliminate a 7–8s latency bottleneck (98% less redundant I/O), and collapsed a multi-step transaction flow into a single click.
• Infrastructure: Built and deployed a privacy-preserving identity verification service on GCP, serving 10,000+ users.
• Backend (Golang): Built a CFD trading platform on Go microservices — Gin, GORM, gRPC/Protobuf, Kafka, Docker/K8s — with ~5x faster dashboard queries and 80%+ test coverage.
• ZK & Cryptography: Optimized 30+ open-source Circom circuits and built a modular testing framework (unit / integration / fuzz) for cryptographic circuits.

• DripLLM — 🏆 1st Place, Team1 Avalanche Builder Launchpad
  • A pay-per-second LLM streaming service: AI agents pay to open a session, receive tokens over SSE, top up automatically, and get cut off once they stop paying.
  • Live demo · video
• Architect Mind
  • An interactive canvas for system architecture design that surfaces structural flaws and suggests optimizations. · Live demo
• Octopus — 🏆 Sui track, Vibe Sui Spring Fest 2026
  • A decentralized privacy protocol on Sui: anonymous transfers plus shielded swaps, staking, and lending — built on ZK-SNARKs, Merkle trees, and Poseidon hashing.

• zkWill — ZK-based digital inheritance system
  • Integrates IPFS, smart contracts, and cryptographic access control; compatible with Taiwan's sealed will framework. Published in Electronics 2026, 15(8), 1642.
• Optimized Cryptographic Circuits (Circom)
  • AES-256-GCM — the first Circom circuit to support 128/192/256-bit AES-GCM.
  • Keccak256 — built at the theoretical-minimum constraint count.
• payLock — 🏆 Best Project, Changsha HOH Hacker House
  • A Sui SDK for secure paid data unlocking, built on Walrus and Seal.
• Invoice-RWA — 🏆 Oasis track, RWA Hackathon Taiwan
  • A secure invoice lottery on Zircuit, using ROFL (TEE) to guarantee the integrity of results.
