Y1 Electrical Engineering @ Hanze University of Applied Sciences, Groningen 🇳🇱
Taiwanese maker who builds embedded systems, designs PCBs, and runs AI trading bots on a Raspberry Pi. I use AI as an ability amplifier and thinking aid, keeping up with tech and AI on a daily basis.
I use LLMs as structured thinking partners, not just code generators. My workflow chains Claude, Gemini, Copilot, and others as debaters, executors, and reviewers in a multi-model loop with checks and balances. → claude-bridges — the full breakdown + tooling.
