What I'm looking for

Wide skillset needed do finish the task.

I've worked on firmware, embedded systems, and desktop software, mostly in C, C++, and Python. My projects include emergency lighting, automotive and medical devices, and an EV battery charger with C unit tests in Unity.

At Novitus, I programmed fiscal devices to high standards as part of a team. I also worked on projects carried out independently, including DrPoket, ESSYSTEM, and ELTE-GPS.

I've designed automotive-class IO PCBs from scratch, along with boards for safety lighting controllers, medical devices, and fiscal devices. My work includes certification, hardware testing platforms in Python, and Django and Flask servers.

I work across complete systems, from device hardware and firmware to desktop, server, web, and mobile apps. As a hobby, I design devices and their cooperating software; I also build and test SMD and THT PCBs at home.
