MeeeetUp FaceID

Face recognition check-in platform for events, offices, hotels, and venues — people register their face once through an invite link, then cameras at entry points recognize them automatically and mark them as arrived, with no tickets, scanning, or app needed. Currently in active development. Sold as a face-ID provider service other products integrate with. Built as a Turborepo monorepo: a Hono + Bun API with layered repository/domain/service architecture, Drizzle ORM + PostgreSQL, a versioned public API with auto-generated OpenAPI docs, Vite + React + TanStack Router consoles, and a distributable cross-platform face-capture SDK (web MediaPipe + React Native ML Kit) that scores faces on-device and uploads only the best frame per person.

Space Navi (スペースナビ)

Space Navi (スペースナビ)

Google CASA Certified SaaS platform for rental space operators. Built as solo developer in ~1 year. Features automated Gmail integration, intelligent email parsing (HTML parsing + regex with AI fallback), AI analytics chat with Generative UI and Smart Context Management (RAG-lite), Stripe subscriptions, and 10-100x query optimization.

Sargalay — LLM API Gateway

Sargalay — LLM API Gateway

Full-stack LLM reselling platform for Myanmar developers. Hono + Bun backend acts as a transparent proxy to 300+ AI models with real-time usage-based billing, balance-first proxy guard, and MMPay/MMQR integration for local Myanmar payments. Includes a Next.js 15 portal with custom i18n (English + Burmese), a streaming AI assistant with search_models tool and conversation summarization, and non-blocking model price caching.

MeeeetUp — Event & Coworking Platform

Event and coworking platform for the Japanese market — hosts publish events, sell and approve tickets, and check attendees in at the door, while coworking operators list spaces, manage rooms, and track who is in the building. Two products ship from one Next.js App Router codebase sharing a feature layer and design system: host-configurable application forms, Stripe payments, per-event email customization with live preview, an analytics dashboard with CSV export, a queued bulk-email worker, and camera-based facial reception with liveness checks, manual search, and QR fallback. Prisma + PostgreSQL, Auth.js social sign-in, feature-flagged releases, Storybook, Vitest, and Playwright.
