Embedded systems engineer at Kavosh Sane Tehran, whose STM32 nurse-call devices now serve ~1,000 hospital beds.

At Kavosh Sane Tehran, I designed a networked nurse-call product line from schematics and PCB layout through STM32 firmware. The products include VoIP audio and audio/video panels, and are deployed across ~1,000 hospital beds.

I built the nurse-station central unit and an STM32H743 intercom with VoIP audio, secure boot, and dual-bank OTA updates. I also developed an RS485-to-TCP gateway and a Python desktop tool for configuration and firmware uploads.

Earlier, I designed automotive laboratory test rigs using Delta PLCs and LabVIEW, and worked on industrial ultrasonic welding equipment. My M.Sc. research focused on cyberattack detection and mitigation in networked wind-turbine control systems; I also teach electronics, ARM microcontrollers, and PLCs.
