What else I Do
Things I'm Building
Just me, AI, and a lot of "what if...?" moments.
Pump BTC
A playful crypto prediction game with satisfying chart-smashing animations and quick, fun interactions.
AI Prediction
When OpenClaw started gaining attention, I wondered: what if an AI agent could analyse Polymarket opportunities, identify arbitrage signals, and help users place trades automatically? That idea became PolyClaw—an experimental product combining prediction markets, AI signals, and automated trading.
AI Zhongyi
While exploring AI-powered health products, I began wondering: what if AI could use facial and tongue scans, together with the holistic principles of traditional Chinese medicine, to help people better understand their bodies? That idea became an AI wellness concept that turns scan results into clear, personalised health insights and everyday guidance.
AI Video Creation
I used AI to turn a written story into visual scenes that matched its theme, then shaped the final piece through shot selection, pacing, and editing.
Kind Words
What's it like working with me?
