Experience

Independent

Independent Developer (Taipei, 2026/07 – now)

  • Built open-skills, an open-source Claude Code plugin with six skills for coding agents.
  • Built a code review pipeline: three reviewers check a change in parallel, each finding is verified against the code before it is reported, and the result is ranked by severity with a verdict on the design.
  • Built a skill that handles PR/MR review comments on GitHub and GitLab: checks each comment against the code, fixes the valid ones and drafts rebuttals with evidence for the rest.
  • Built an interactive codebase walkthrough that reads code in a git worktree pinned to a commit, cites every stop as file:line, and saves a reading record.
  • Built a harness for agent development: init scaffolds the project’s CLAUDE.md and long-term memory, harness-flow dispatches work to an implementor agent and marks it done only after a reviewer agent passes it, handoff saves decisions, dead ends and next steps so a fresh session can resume.
  • Published an article on using git worktree to run parallel development, including multiple coding agent sessions on one repo.
  • Stack: Claude Code plugins, agent skills, subagents, Git, GitHub CLI, GitLab CLI

BSOS - Isle Finance

  • Coordinated external audits and hardened the protocol’s security.
  • Researched lending, DEX and auction mechanisms.
  • Stack: Solidity, Foundry, Leveraged Yield Farming, Lending/DEX/Auction

FiO

Blockchain Developer (Taiwan, 2021/02 – 2023/12)

  • Introduced an upgradeable architecture so the team could iterate without redeploying.
  • Built ERC20 staking systems and an ERC721 marketplace.
  • Stack: Solidity, Foundry, Hardhat, ERC20, ERC721, Upgradeable Proxy (Transparent/UUPS)
