I build custom desktop and web applications using Electron, React, and Node.js. Services include full-stack desktop apps packaged as Windows installers, REST API development, automation tools, real-time WebSocket/WebRTC applications, and SQLite/PostgreSQL database design. Recent work includes Guitar Jam, a real-time peer-to-peer desktop app, and JusticeDenLister, an automated eBay listing and repricing tool. I write clean, well-commented code and communicate clearly throughout every project. Available immediately for hourly or fixed-price work.
