Firmware Developer - Level 1 at Reliable Controls
Canada
Summary
🤩
Rockstar🎓
Top SchoolPaul Sajna is a curious and self-driven firmware developer with 11 years of hands-on experience across software and embedded domains, currently building firmware at Reliable Controls. He transitioned from a Software Developer role into firmware after four years of professional software work, bringing strong backend and systems problem-solving skills honed at companies like Taskoli and through early technical roles. Paul contributes to open-source embedded projects in Rust—adding Circuit Playground Express support to atsamd-rs—and has improved cross-platform stability in the popular OpenRCT2 project by addressing POSIX locking compatibility. Based in Canada, he pairs practical electronics tinkering and a home-lab mindset with formal training from Camosun College, often bridging low-level hardware constraints with higher-level software design.
