Full-stack developer who ships AI-powered products end to end — from the rough idea to the deployed thing people actually use. Based in Singapore 🇸🇬.
I started in classic full-stack web/app work and have been steadily moving toward AI and agent tooling — not as a buzzword, but because it's where the interesting, unsolved problems are right now. I like owning a project across the whole stack: design, build, deploy, and the unglamorous parts in between. Most of what I make starts as a personal annoyance I wanted gone.
full-stack roots → AI / agent tooling → products that ship
I take things from zero to deployed — web apps, CLIs, MCP servers, and the infrastructure around them. A few I'm proud of:
| Project | What it does |
|---|---|
| whatsapp-mcp-extended ⭐17 | Production WhatsApp MCP server — 26 tools, webhooks, anti-ban, Docker. The maintained successor to an abandoned original. |
| tokenusage | Blazing-fast Rust CLI tracking AI token usage across Claude Code, Codex, Gemini & OpenCode. |
| claude-code-sync ⭐8 | Sync your Claude Code setup across machines via GitHub, with age-encrypted secrets. |
| tandem | Browser MCP server — lets AI agents drive your real, authenticated Chrome, not a throwaway headless one. |
| mnemon | Contributed on-device Qwen3-ASR transcription — privacy-first, multilingual, CPU-fallback. |
…plus ongoing contributions to OpenClaw, ccstatusline, resurrect.wezterm, and other open-source agent tooling.

I'm open to freelance and collaboration — especially building AI-powered tools and products end to end. If you've got something you want shipped, let's talk.

Always learning — currently deep in Rust, local inference, and the MCP ecosystem. Off-screen I read, fall down science-and-maths rabbit holes, and have an enduring weakness for mechanical keyboards, Star Trek, and cats 🐈.
Building to learn, shipping to prove it.
