Fintrack is a personal portfolio tracker that aggregates stocks and crypto positions into a single terminal-style dashboard. It pulls real-time market data from Finnhub for equities and Binance for cryptocurrencies, displaying live prices, P&L, and asset allocation.

The web app uses a dark terminal aesthetic with lime green accents, designed mobile-first with a max-width layout that feels native on phones. It features a watchlist screener, interactive candlestick charts with order book depth, and a tape feed for real-time trades.

All API calls route through Cloudflare Workers proxy endpoints to handle CORS and keep API keys server-side. The Binance integration uses both REST polling and WebSocket streams for live ticker updates, while Finnhub provides real-time stock quotes.
