Bolymarket

Full-stack prediction markets UI · In progress

Next.js / React / TypeScript / Tailwind CSS

Polymarket’s product surface is complex (category navigation, live odds, charts, sports, mobile chrome), and building a faithful read-only experience requires careful separation of static event data from high-frequency price updates without melting the React tree.

Deployed on Vercel with 7 user routes, 7 REST API routes, home/category/event-detail flows, live price updates, CLOB-backed charts with simulated fallback, bookmarks, dark mode, mobile chrome, Swagger API docs, and a large Vitest suite. Trading, wallet connect, and real auth are intentionally visual-only.

BabyFlow Tracker

Full-stack PWA · Live

React / TypeScript / TanStack Router / FastAPI

Caregivers need a fast phone-first way to log feeds, diapers, sleep, and health events—and share that timeline with partners without losing data when connectivity drops.

End-to-end monorepo with auth, RBAC, insights, Web Push reminders, bilingual UI, and CI/E2E coverage.

Local-First AI Chat

Local-first AI stack · In progress

TanStack Start / React / FastAPI / PostgreSQL

Most AI chat tools depend on hosted APIs. This project runs chat, persistence, and inference entirely on localhost with a one-command dev stack.

Working local MVP with typed API contracts, Alembic migrations, SSE streaming, and automated Vitest, Playwright, and pytest coverage.
