I’m looking for an experienced developer to help finalize and harden a nearly complete production-grade sports card monitoring bot. The system is already live, deployed, and scraping real marketplace data — the remaining work focuses on VPN stability, accuracy improvements, and 24/7 reliability. Core Objective Maintain real-time marketplace monitoring and keep the bot running 24/7 with stable VPN rotation. Even detecting 2–3 profitable cards per week is considered a success. Key Features (Already Implemented) ✅ Production Server – Deployed on DigitalOcean ✅ Live Marketplace Scraping – Vinted & Wallapop (real data) ✅ Professional Dashboard – Bootstrap 5 web interface ✅ Database – Fully designed MySQL schema ✅ Email Alerts – SMTP notification system ✅ Safe Scraping Logic – SSH-preserving scraping (15–30% success rate currently) ✅ Export Tools – CSV / Excel exports ✅ Automated Deployment – One-click setup scripts ✅ Complete Documentation – Setup & usage guides included Final Task Breakdown 1. Marketplace Intelligence Identify the number of likes/favorites per card listing Compare listed prices against historical sold prices from secondhand marketplaces (eBay integration framework already in place) Detect profitable arbitrage opportunities automatically 2. VPN Stability & Rotation (High Priority) Fix SSH disconnection issues caused by VPN reconnects Improve VPN rotation logic using Surfshark .ovpn profiles Ensure SSH session persistence during IP changes Implement failover handling for unstable VPN nodes Increase scraping success rate to 70–85% Update and stabilize [login to view URL] 3. Data Parsing & Accuracy Improve HTML parsing logic for marketplace listings Extract structured card data: Player Year Condition Metadata / attributes Reach ~90% parsing accuracy Optimize: [login to view URL] [login to view URL] 4. Final Production Testing Run full end-to-end live scraping tests Validate VPN stability over long execution periods Confirm database consistency and integrity Verify dashboard, alerts, and exports work flawlessly Ensure continuous unattended operation What You’ll Get Access To Complete Codebase 90+ well-structured and documented PHP files Working live scrapers (real marketplace data) Client-ready dashboard UI Optimized MySQL database schema Automated deployment scripts Infrastructure DigitalOcean production server access Domain & SSL configured MySQL credentials provided Surfshark VPN subscription included Business Logic Automatic profit & arbitrage detection Price comparison framework (eBay ready) Email alert system ROI analysis (50×–250× opportunities identified) Final Deliverable A fully production-ready Advanced Sports Card Monitoring Bot with: Stable VPN rotation Reliable live data scraping Accurate card parsing Real-time price comparison 24/7 uninterrupted execution This system is already 95% complete — the focus is on hardening, optimization, and reliability, not starting from scratch.
