Summary
👤
Senior🎓
Top SchoolPatrick Van Oosterwijck is an owner and principal engineer with 12+ years of hands-on experience turning product ideas into shipped electronics and firmware, and two decades of deep embedded systems expertise. He designs everything from rapid MVPs on off-the-shelf modules to fully custom PCBs, power systems (notably LiFePO4wered/Pi+), PoE solutions, and energy-harvesting hardware, and has launched multiple products via successful crowdfunding. Patrick is also an active contributor to prominent open-source microcontroller projects like MicroPython and CircuitPython, adding board support and networking integrations for ESP32 and RP2040 platforms. He pairs low-level analog and SoC design experience from chip development with higher-level firmware, cloud integration, and manufacturing/test-fixture know-how, enabling dramatic cost reductions for over-designed systems. Based in Longmont, CO, he offers contract work to quickly move concepts to market or to iterate on vetted designs for faster time-to-revenue.
