i build things for problems i keep having. the full set is at tzyh3243.com — six projects, ranked by depth of work.
Most recently i've been auditing my own stock scanner in public: 35 tests, 0 survivors, and the best-case portfolio loses to SPY. i published it anyway.
the site's email button copies my address instead of linking it. scrapers don't get one; you do.
- Momentum - reads 5,500 tickers a day, three passes, and almost nothing survives. i also just wanted to stop missing the move.
- momentum-research
- the pre-registered audit of the scanner above. kill criteria were committed before the data existed, so i couldn't flinch.
- News4u - a newspaper with one reader, printed by robots every night. if nothing happened, it says so.
- Track·Y
- golf swing analysis that runs in your browser. the video never leaves your phone; only the numbers do, and only if you ask the AI coach. i also just wanted to fix my swing.
- Switchyard
- faker.js for the trolley problem. yes, i built a whole bench to settle a pub argument.
- 1PI3CE - a night chart of the Grand Line you sail instead of scroll. i lost the argument, so i built an ocean instead.
- vibe-translator
- a Claude skill that rewrites content so it reads native, not translated. ships a validator, because "sounds fine to me" is not a test.
- clear-eye
- three Claude skills for seeing what others miss: forensic-read, second-order, pre-mortem.
- awesome-claude-skills
- open PR adding vibe-translator and clear-eye. still open.
- awesome-claude-skills
- same PR, other list. also still open. i am patient.
