An online tool that turns long Chinese text into a single MP3 — up to 60,000 characters (about 3.6 hours of audio) per run, synthesised in chunks and merged server-side.

• Rapid MVP iteration with AI coding tools; then hardened the API and shipped it to production myself
• Implemented rate limiting, text/body caps, atomic job admission, a session IDOR fix, a CORS allowlist, and bounded session storage with process eviction
• Deployed solo on an Alibaba Cloud instance: nginx virtual host, systemd unit, Let’s Encrypt TLS with auto-renewal

• TypeScript
• Node.js
• Express 5

Final year project, now deployed: two tools over one shared algorithm core — an explorer that reproduces the paper’s three algorithms and cross-checks them against exact enumeration, and a drag-and-drop network topology designer.

• Reproduces the three algorithms from arXiv:2502.05877 (the paper is not the author’s work; this is reproduction and engineering)
• Both tools import one implementation from packages/core, so the explorer’s cross-checks exercise the same code the tool ships
• Refuses graphs with no sink-free orientation and names the cause; states when the paper’s δ(G) ≥ 3 bounds do not apply instead of misreporting

• React
• TypeScript
• Vite
• Tailwind CSS

An assistant for the game master of an in-person werewolf (Mafia) table — it never forgets the order, miscounts the antidote, or plays favourites. Opens 12 player seats plus one game-master seat, with a workshop for authoring boards and roles.

• Three-layer model — board rules → roles → abilities: cross-role rules like "same-target guard+antidote kills" or the mech-wolf learning map belong to the BOARD, not to any single role
• Board studio: describe a board in one sentence and an LLM (DeepSeek) assembles it from a template allowlist; if validation fails it substitutes a legal role and shows you exactly what changed
• Engine covers interrupts mid-day, death triggers, a 1.5-vote sheriff implemented in integer half-votes (no float error), tie-break PK re-votes, and neutral / dynamic factions
