Sports Card Monitoring Bot Optimization

Description: I’m seeking an experienced developer to finalize and harden a nearly complete, production-grade sports card monitoring bot. The system is live, scraping real marketplace data, and already deployed — the remaining work focuses on VPN stability, accuracy improvements, and 24/7 reliability. Core Objective: Maintain real-time marketplace monitoring and ensure the bot runs uninterrupted with stable VPN rotation. Detecting even 2–3 profitable cards per week is considered a success. What’s Already Built: - Production Server – Deployed on DigitalOcean - Live Marketplace Scraping – Vinted & Wallapop - Professional Dashboard – Bootstrap 5 web interface - Database – Fully designed MySQL schema - Email Alerts – SMTP notifications - Safe Scraping Logic – SSH-preserving (currently 15–30% success) - Export Tools – CSV / Excel - Automated Deployment – One-click setup scripts - Complete Documentation – Setup & usage guides Remaining Tasks / Scope of Work: Marketplace Intelligence Identify likes/favorites per card listing Compare listed prices to historical sold prices (eBay integration in place) Automatically detect profitable arbitrage opportunities VPN Stability & Rotation (High Priority) Fix SSH disconnections caused by VPN reconnects Improve Surfshark .ovpn rotation logic Ensure SSH session persistence during IP changes Implement failover for unstable VPN nodes Increase scraping success rate to 70–85% Update and stabilize [login to view URL] Data Parsing & Accuracy Improve HTML parsing of listings Extract structured card data (Player, Year, Condition, Metadata/Attributes) Achieve ~90% parsing accuracy Optimize [login to view URL] and [login to view URL] Final Production Testing Run end-to-end live scraping tests Validate VPN stability over long periods Confirm database consistency Verify dashboard, alerts, and exports work flawlessly Ensure continuous unattended operation Access You’ll Receive: Full codebase (90+ well-documented PHP files) Live scrapers & client-ready dashboard UI Optimized MySQL schema Deployment scripts DigitalOcean server access, domain & SSL Surfshark VPN subscription Business logic including automatic profit detection, price comparison, and ROI analysis Final Deliverable: A fully production-ready sports card monitoring bot with: Stable VPN rotation Reliable live data scraping Accurate card parsing Real-time price comparison 24/7 uninterrupted operation Note: The system is already 95% complete. This project is focused on hardening, optimization, and reliability, not building from scratch.
