I’m a results-driven Embedded Systems Engineer with 8 years’ experience and B.Sc. Robotics & Mechatronics, who delivers end-to-end custom electronics solutions. Key strengths: - Firmware: C/C++ & RUST for microcontrollers, Verilog & System verilog for FPGA. - Hardware & PCB: Altium/KiCad designs. - Software: Qt/C++ desktop apps and embedded linux. I work hand-in-hand with clients to transform ideas into robust, production-ready embedded systems - covering everything from initial concept and prototyping to final integration and support. Let’s discuss your next embedded project!

I bring 15+ years of international experience across firmware, hardware, PC-system software, and bespoke applications for embedded systems. I take products end-to-end—from concept and architecture through electronics, firmware, mechanical design, and production. In-house, I handle mid-scale builds (down to 0402 and fine-pitch BGAs) with pick-and-place, reflow, and full validation, source components globally, and coordinate seamlessly with external PCBAs for higher volumes. Instead of juggling multiple suppliers, you get one partner who integrates hardware, software, and mechanics into a cohesive, production-ready solution. If you’re looking to turn an idea into a reliable, manufacturable product, let’s connect.
