I have hands on experience designing custom PCBs, circuit schematics, and production ready board layouts for electronics and embedded projects. I work with KiCad and Altium Designer to turn ideas, schematics, and reference designs into clean, reliable PCB designs. My experience includes 2 layer and multi layer PCBs, component placement, routing, power management, microcontroller boards, Arduino, ESP32, STM32, sensors, communication interfaces, and PCB manufacturing files. I focus on clean layouts, correct footprints, design for manufacturing, signal integrity, and accurate Gerber/BOM outputs so your design is ready for prototyping or production. I can help with: • PCB schematic & layout • KiCad & Altium design • ESP32, STM32 & Arduino boards • Custom electronics & embedded hardware • Power electronics & DC DC circuits • PCB redesign and modifications • Gerber, BOM & manufacturing files • DFM and design review
