About Me

Embedded Software Engineer specializing in Safety-Critical Systems

Hello, I'm Sani

I'm an embedded software engineer with over 10 years of experience building safety-critical systems across aviation, railway, and industrial domains. My journey has taken me from designing simple home automation devices to developing certified software for mission-critical applications.

Currently working at TTControl in Vienna, I develop safety HMI devices and demo applications for complex multi-core ARM platforms, combining low-level C programming with modern frameworks like Qt6 and GStreamer.
