Communications systems engineer working on infrastructure that has to perform when failure is
not an option — mission-critical communications, enterprise connectivity, RF systems, and
in-building coverage. Day-to-day work spans cellular and public-safety DAS/BDA, fiber, frequency
coordination, and land mobile radio, from field implementation and troubleshooting through
long-term system management. Backed by a semiconductor test-engineering background that built a
foundation in structured troubleshooting, systems thinking, and hardware design.
