Work with me

The work, mapped to what it demonstrates. Each claim links to the thing itself.

What this site demonstrates

• A three-app monorepo shipped to Cloudflare Workers in three days: this hub, the arena, and the daily game — inventoried on /projects (the two new apps with receipts; the earlier projects carry honest statuses, post-mortems included).
• AI integration treated as a budget problem: live runs sit behind a bot check, charge both signed-session and hashed-IP daily quotas, and reserve worst-case cost under a local daily ceiling. Each lane makes one provider attempt through Gateway; a Gateway or transport failure becomes a lane error rather than a second attempt. An admission refusal ends the stream; a model refusal is one lane’s paid verdict. Both leave replay as the visitor’s choice. The bases are printed on the about page; the build’s own bill is a receipt on the build log.
• Product design around deterministic scoring: the arena’s winner rule is correct → cheapest → fastest, and the race every model failed identically (sort-second) stays published on the arena.
• Test and gate discipline: a drift alarm that re-scores every fixture, a blocking banned-words lint, 516 unit tests as of July 31. The pipeline behind them — and the bill — is on the build log.
