Senior Lead Engineer specializing in secure payments, cryptography, POS architecture, SoftPOS, and telecommunications.

I currently work as a POS Architect at MultiSafepay, focusing on payment systems, cryptography, terminal architecture, and end-to-end POS/SoftPOS solutions. My background also includes telecommunications engineering at EF Data, now Comtech, and Fairchild, with experience in satellite communications, RF systems, DSP, FPGA, and modem design.
