Senior🎓
Top SchoolChris Ruehl is an engineering-driven founder and owner of GTSYS Limited with 12+ years delivering RFID solutions for automatic vehicle identification, tolling, access control, and license-plate tag design. He combines hands-on C/C++ systems programming experience from early work on ISP and VoIP platforms at IBM Germany with product leadership gained as CTO at X-IT Management and now as Managing Director. Based in Hong Kong, he specializes in end-to-end RFID product development—hardware-aware firmware, system integration, and the commercial deployment challenges of tolling infrastructure. His background in telecommunications engineering informs a pragmatic approach to reliability and interoperability in real-world transport and access systems. Chris’s career blends deep technical craftsmanship with entrepreneurial execution, having taken niche RFID technologies from concept to market. A detail that sets him apart is his long continuity in the space: a decade-plus focus on AVI/tolling that yields domain expertise often missing in generalist IoT teams.
