Ján Lizúch

I am an Embedded Systems and Electronics Engineer specialising in STM32 firmware development, low-level driver design, mixed-signal electronics, vacuum electronics, ultra low noise, ultra low power and power converter design. My work combines deep hardware knowledge with clean, reliable embedded software, allowing me to design complete solutions from the analog front-end all the way to firmware and system integration.

I develop bare-metal STM32 applications, LL drivers, timing-critical routines and control algorithms. On the hardware side, I design analog, digital and mixed-signal circuits, low noise signal paths, sensor interfaces, active filters, measurement front-ends and PCB layouts optimised for low noise and signal integrity.

I also work in power electronics, including power converters (DC/DC, AC/DC, DC/AC, AC/AC), SMPS topologies, sensing, isolation, control (analog or digital), signal conditioning, EMI-aware PCB layout practices and more.

My added value lies in my ability to combine firmware, electronics and system-level thinking. Whether you need a single driver, a custom mixed-signal module, a PCB design or a full embedded subsystem, I deliver solutions that are documented, stable and ready for integration.

I enjoy working with companies building innovative hardware — from prototypes to production-ready designs. If your project requires precision, reliability and hands-on engineering, I can help.
