projects

anthonyta.dev — personal hub & E2EE command center2026

Next.js · React · TypeScript · Cloudflare R2you are here

·Dual-face platform on one codebase: a public portfolio aggregating six live sources (GitHub GraphQL, Riot API, app databases, transit and weather feeds) through a guarded connector layer that degrades to sample data on any upstream failure — and a private, passkey-gated command center used daily for finances, training, meals and scheduling.
·Client-side end-to-end encryption for all personal data: AES-GCM envelopes with path-bound AAD, WebAuthn passkeys with PRF-derived vault unlock, Shamir secret-sharing paper recovery, and a crash-tested master-key rotation state machine — the server only ever stores ciphertext.
·Public/private boundary enforced with a strict-nonce CSP, HSTS preload, and an adversarial Playwright suite that derives every route from the filesystem and proves guests receive byte-identical 404s on every owner route; 1,790+ unit tests on branch-protected CI across 200 merged PRs.

Ishin — JP⇄EN translation that lands as meant2026

Next.js · TypeScript · Claude APIishin.io ↗

·Streaming JP⇄EN translator where naturalness beats literal; per-direction models and generating only the selected register cut per-translation output tokens ~50%.
·Naturalness-check mode verdicts your own JP or EN in real time — register-aware feedback with the verdict line styled as it streams.

Riichi — solo mahjong learning platform2026

SvelteKit · TypeScript · Postgres · Rust/WASMlive ↗

·Pure-functional riichi engine for solo play against three rule-based opponents, enforcing the complete ruleset (riichi, furiten, kan, abortive draws, double ron) with yaku detection and scoring delegated to a Rust/WASM library validated on millions of Tenhou hands.
·Deterministic replay logging reconstructs any game from its wall and inputs — Postgres-backed history, in-browser playback, and export to the MJAI and tenhou.net/6 formats consumed by the Mortal AI reviewer.
