I want a lean, web-based trading platform built around reliable, real-time market data for Bitcoin and Ethereum. My priority right now is the market-data layer: live price feed, depth of book, recent trades, basic charting and latency figures I can trust. If you have opinions on the best exchange websockets or aggregation services, bring them—I’m open, but whatever solution we choose must update seamlessly without constant page refreshes. Down the line I may layer in automated bots and broader portfolio tools, so an architecture that can scale to those modules will be appreciated, but version 1 is strictly about data display and a clean, intuitive UI. Deliverables (v1) • Fully functional dashboard showing real-time BTC & ETH quotes, order book and trade tape • Lightweight REST/WebSocket back-end that feeds the front-end without noticeable lag • Simple account/auth layer so I can demo it privately • Brief technical read-me explaining data sources, rate limits and how to extend the code If you’ve previously wired up Binance, Coinbase Pro, Kraken or another exchange API and can point me to latency metrics, that’s a plus. Let me know what stack you prefer and roughly how long you’ll need to reach a clickable prototype.
