I’m Ronald A. Buhian, a Senior Software Engineer and Team Lead with 20+ years of experience delivering enterprise applications end-to-end—from gathering requirements to deploying production systems. I’ve built and maintained software using C# and ASP.NET, WPF with DevExpress, and modern web frameworks (Laravel, React, Ruby on Rails), with a strong focus on reliability, maintainability, and practical delivery in Agile teams. Beyond core software, I also specialize in integrating audio-visual and control systems using Crestron and Q-SYS, including scripting and network-based integrations. In recent work, I’ve led development of a C#/WPF ticketing system, created Tekla automation plugins, and built an AI-powered Accounts Payable automation workflow that extracts structured invoice data and stores it in PostgreSQL—reflecting my blend of engineering depth, leadership, and curiosity for new technologies.
