Embedded Systems Engineer
Firmware • RFID Systems • RTLS • IoT • Hardware–Software Integration
Embedded software engineer with firmware development and PCB design experience across industrial and IoT systems, currently specializing in UHF RFID/RTLS. I build reliable embedded software close to the hardware, real-time data ingestion, device communication, structured payload construction, and the integration work that takes a system from bench prototype to production deployment.
Most recently, I built and deployed a production RFID Smart Space Portal pipeline at Acceliot on Impinj R700 and Zebra FXR90 readers, achieving 99.8% average accuracy in real-world retail testing. My focus is on the parts of a system that have to actually work in the field: reliability, debugging, clean device-to-system data flow, and measurable outcomes.
