Backend engineer in Taiwan. I write Go and C#, practise TDD and DDD in earnest, and build tooling that keeps AI coding agents inside real engineering discipline instead of letting them generate spaghetti faster than anyone can read it.

- Writing a daily series on quantitative trading — strategy blocks, vectorised backtests, and why a 300% backtest still loses money once slippage is priced in.
- Building spec-driven development workflows and Claude Code skills, so that Ubiquitous Language, vertical slices, and TDD survive contact with an AI agent.
- Shipping small Go services and CLI tools: schedulers, git summarisers, stock analysis.
