Projects

The meta project. A chat-first AI portfolio that demonstrates the candidate rather than describing him — the recruiter reading this case study is doing so *inside* the very surface the case study describes. 5-tool GenUX (showProjects / showTimeline / showQuoteGrid / showProjectsList / generateResume), project-scoped RAG with on-the-fly source-quota overrides, streaming citations rendered BEFORE the assistant text, anonymous-quota economics with multi-key Gemini rotation, system-prompt redaction layer as positioning policy. Next.js 16 + AI SDK 6 + Gemini 3.1 Flash Lite + Supabase + pgvector.

Full-stack golf-society management platform for a Tokyo-based golf society. Live scoring with offline-first localStorage sync, WHS-compliant handicaps alongside Japanese Peoria / Callaway formats, a 1,932-course Rakuten GORA-enriched Japanese database with Mapbox GL satellite hole maps, season-long standings, multi-day event tours, and a Capacitor iOS shell — with a documented commercial roadmap to spin it up as Pitchmark, a multi-tenant white-label platform for golf societies across APAC.

AI receipt + bank-statement ingestion SaaS built solo for APAC freelancers and SMEs. Four shipped tax jurisdictions (JP, HK, SG, MY), eight locales, ten public tax calculators, native iOS + Android, and a cross-platform tax-rules engine ported across TypeScript, Swift, and Kotlin.

AI menu-translation platform for restaurants and bars. Gemini-powered OCR ingests paper menus and PDFs, translates to 30+ languages with culinary context, and runs the operational stack on top — QR codes per table, diner self-ordering in their language, and a real-time Kitchen Display System that translates special requests on demand.

A free, client-side Markdown editor with live preview and one-click export to PDF, HTML, Google Docs, Notion, Dropbox, and GitHub. Built end-to-end as a 24-hour vibe-coding sprint, then hardened over the following week into an 18-language UI. No sign-ups, no tracking — the document stays in the browser.

The only public OSS repo in this portfolio. A Python multi-agent CLI that mines Reddit pain-points and generates AI-coding-agent-ready BRDs / PRDs / Agile plans. Six-stage pipeline (extract → cluster → consolidate → opportunities → validate → docs) with dual-model routing — Gemini Flash for per-lead volume, Gemini Pro for judgment. The cross-portfolio loop closes here: this tool generated the AI Canvas BRD that built Pico.

A solo-built Vue 3 + Supabase pub-management platform for a Tokyo British pub. The interesting part is the back office: admin uploads a music event poster, Gemini 1.5 Flash reads it and returns structured bilingual EN/JA copy that auto-fills the event form. Plus batch Gemini translation for menus, AI food-image disclaimers shipped same-day, Stripe-backed merch pre-orders, YouTube + OBS broadcast integration, and 22 admin pages the landlord runs without a deploy. 212 commits across 16 months.

Two-product AI-first digital-signage suite for cafés, offices, and small venues. Pico Cloud is a Vue 3 + Firebase dashboard with a 2,912-line in-product agent (Gemini 3 Flash + 3.1 Pro + 2.5 Flash Vision, 43 typed tools, multi-step generation with visual self-critique). Pico Player is a Vutron/Electron app engineered for unattended displays — heartbeat, memory monitor, crash counter, hybrid Firestore-state + Socket.IO-control realtime, and offline-aware cached content for flaky café WiFi.
