Rockstar🎓
Top SchoolMartin Hubáček is a hardware and firmware designer with 11 years of experience building low-power, manufacturable embedded products and IoT systems from prototype to production. Based in Zlín, Czechia, he develops open-source hardware and firmware at HARDWARIO, working with LPWAN stacks (LTE-M, LoRaWAN, NB-IoT), Zephyr RTOS, and diverse interfaces like RS-485/Modbus, Ethernet and USB. His background spans microcontroller systems, wireless charging and motor/LED controllers from an earlier R&D role, giving him strong cross-layer expertise in analog, digital and software integration. Martin is an active open-source contributor, adding board support and display/peripheral integrations to projects such as LiteX-boards and the InfiniTime smartwatch firmware. He emphasizes design for manufacturability, testability and energy efficiency, often implementing practical hardware-specific firmware adaptations that accelerate product bring-up. An engineer by training (VSB Ostrava) with roots in low-current electronics, he blends hands-on soldering-level know-how with system-level design.
