Summary
🤩
Rockstar🎓
Top SchoolBenjamin Björnsson is an embedded engineer with eight years of hands-on experience designing and integrating hardware-first firmware for safety- and performance-critical systems. Based in Jönköping, Sweden, he has progressed from trainee and research roles in automotive suppliers to tech-lead responsibilities and now runs his own consultancy, blending product-focused pragmatism with team leadership. He is an active contributor to the Zephyr RTOS, adding STM32C0 support for peripherals like GPIO, ADC, RTC, DMA and PWM—demonstrating deep device-tree and board integration expertise in a widely used open-source RTOS. Comfortable across low-level driver development, board bring-up and system architecture, he pairs a physics degree with practical manufacturing and inflator development background that helps him bridge theory, hardware constraints and production realities.
