Senior🎓
Top SchoolSaim Saygın is a Senior Software Engineer in Istanbul with over a decade of experience designing and implementing embedded firmware and Linux-based software for industrial and payment systems. He has delivered secure, low-level applications on resource-constrained hardware—from ARM Cortex microcontrollers to ARM-11/Cortex-A platforms—bringing expertise in C/C++, Python, OpenSSL and a wide range of comms protocols (ISO 7816/14443, TCP/IP, CAN, Modbus). His background spans safety-critical public transit control systems using model-based Simulink code generation to payment terminal security and protocol implementation, showing strong domain breadth across reliability and security. At Afiniti and previously at Diebold Nixdorf and Verifone he focused on production-grade, secure embedded solutions, often bridging hardware constraints and higher-level data formats like JSON/SQLite. Trained in Control Engineering at Istanbul Technical University, he combines control-theory rigor with practical firmware craftsmanship and a track record of shipping mission-critical systems.
