Polymarket Crypto Hedge Bot

I am looking for an experienced developer to build an automated trading bot integrated with the Polymarket API.

The bot will operate on short-term crypto prediction markets (e.g., BTC 5-minute markets) and must execute trades automatically based on predefined mathematical conditions.

This is NOT a simple scraper — I need a production-ready trading system with real-time execution and proper risk management.

Core Requirements:
• Integration with Polymarket API
• WebSocket support for:
• Orderbook data
• User fills
• Automatic order execution
• Limit order placement only (no market orders)
• Handling of partial fills
• Position tracking logic
• Basic risk control system
• Configurable parameters (position size, thresholds, timing rules)
• Logging and error handling

Technical Requirements:
• Python (preferred) or Node.js
• Experience with Web3 / EIP-712 signing
• Understanding of crypto trading systems
• Async architecture
• Clean, well-structured code
• Deployment-ready (VPS compatible)

Nice to Have:
• Experience building trading bots
• Experience with prediction markets
• Experience with Polygon network
• Low-latency trading systems

Please include:
• Relevant past work
• Tech stack proposal
• Estimated timeline
• Estimated budget

Long-term collaboration possible
