About

I'm a systems-focused engineer and architect based in Bellevue, WA. I specialize in building reliable, scalable applications that operate beyond the browser - integrating hardware, networks, and real-world workflows. My work spans frontend architecture, device communication, and end-to-end system design.

At Rhombuz LLC, I architect and deliver production systems for enterprise clients, lead cross-functional teams, and establish engineering standards across products. I focus on making complex systems work reliably in real-world environments
