Barnabas K.

I design, review and debug embedded electronic hardware from schematic through PCB manufacturing and prototype bring-up. My main focus is practical, manufacturable electronics: mixed-signal and analog circuits, MCU-based hardware, power supplies, industrial interfaces, and custom test and measurement systems. I can help with: • Schematic design and design review • Multi-layer PCB design and existing PCB modifications • Analog and mixed-signal circuitry • Power supplies, protection and interface circuits • MCU-based embedded hardware • Component selection, BOM and manufacturing documentation • PCB bring-up, measurement and hardware troubleshooting • Prototype assembly and validation • 3D PCB/enclosure integration EDA: Altium Designer, KiCad Embedded: STM32, Microchip, C/C++, FPGA/CPLD logic Test & Measurement: LabVIEW, automated test systems, hardware validation Lab: oscilloscope, logic analyzer, multimeter and hands-on PCB debugging Mechanical: Solid Edge, Fusion 360 I am comfortable working both from a new set of requirements and from an existing design that needs review, redesign, troubleshooting or preparation for manufacturing. Available for ongoing development as well as focused schematic, PCB and debugging projects.
