About
I'm a Technical Support Engineer focused on VoIP and cloud communications. Day-to-day I diagnose SIP call failures, resolve message-delivery issues, and handle high-priority incidents in a NOC environment.
Before specializing in voice, I worked across web development and systems administration. I'm passionate about open source and continuously learning new tools to sharpen my craft.
