Lukasz W.

I design complex, production-ready electronic hardware in Altium Designer, backed by 20+ years of electronics engineering experience in high-speed PCB design, embedded systems, and industrial product development. I specialize in taking complex electronics concepts from initial design through validation and into reliable, manufacturable products. With 20+ years of professional experience, my core expertise includes: • Altium Designer PCB development • High-speed digital design • Embedded hardware and firmware • Industrial electronics • High-reliability product development I have completed 50+ professional PCB designs, including complex multi-layer boards up to 10 layers, high-voltage battery systems, industrial controllers, EV charging electronics, ATEX-certified electronic systems, and safety-critical embedded devices. My focus is not creating prototypes that only work on the bench. I design hardware that is manufacturable, reliable, EMC-compliant, and ready for real-world deployment. My designs are created with production, reliability, EMC compliance, and long-term field operation in mind.
