Engineering Excellence Meets Real-World Reliability
I’m Joshua, a professional engineer and technical consultant based in Spokane, Washington. With over 15 years of specialized experience in telecommunications, unified communications (UCaaS), and VoIP engineering—alongside six years of running a dedicated consulting practice—I partner with businesses to architect, optimize, and troubleshoot complex communication systems.
Over the years, I’ve built a reputation for rolling up my sleeves and solving the toughest architectural and diagnostic challenges. Whether it's deep-dive SIP signaling analysis using Wireshark and Linux-based tools, fine-tuning Kamailio SIP proxies, or custom backend API integrations and platform administration, my goal is always to deliver rock-solid reliability and seamless performance.
