About this role
PHP, Python, Amazon Web Services, Node.js, API, AWS Lambda, GraphQL, REST API · I need a bot that focuses exclusively on the US stock market, streaming real-time stock prices for NYSE, NASDAQ, and AMEX tickers. The goal is to surface fast, accurate quotes with optional contextual headlines so users can act immediately.
Scope of work • Connect to a proven real-time data feed (e.g., IEX Cloud, Polygon, or similar) and handle rate limits gracefully. • Allow users to request any listed symbol and receive the latest price, day range, volume, and percentage change. • Push automated alerts when a symbol crosses user-defined thresholds. • Expose the service through a simple chat interface or REST/GraphQL endpoint; whichever you’re most comfortable building robustly. • Deploy to a lightweight cloud host (Heroku, Vercel, AWS Lambda, etc.) with clear environment variable instructions.
Acceptance criteria 1. A running bot accessible by URL or chat handle that returns real-time prices in under two seconds for the three exchanges mentioned. 2. Source code with concise README covering setup, API keys, and how to add new symbols. 3. Logging that shows each request, response time, and any API errors for easy monitoring.
