PCB Design & Embedded Systems Engineer

CircuitDesk • Freelance

Jan 2019 - Present • 7 yrs 8 mos

Design and develop custom electronics solutions for startups, product developers, engineers and businesses. My work covers PCB design, circuit schematics, PCB layout, hardware prototyping and embedded programming. Key responsibilities and achievements: • Created PCB layouts from circuit concepts and existing schematics • Designed single, double-layer and multilayer PCB layouts • Developed schematics and converted them into production-ready PCB layouts • Prepared Gerber, NC drill, BOM and Pick and Place files • Created custom footprints, symbols and board outlines • Performed DRC and ERC checks to identify design issues • Redesigned existing PCBs to improve layout and manufacturability • Developed Arduino, ESP32, STM32 and Raspberry Pi projects • Integrated sensors, modules, displays, connectors and control circuits • Worked with SMT and THT component layouts • Prepared 3D PCB models and mechanical design references • Supported prototype development and manufacturing preparation Tools and platforms include Autodesk EAGLE, Fusion 360 Electronics, KiCad, EasyEDA, Altium Designer, Proteus, DipTrace, Arduino IDE, PlatformIO, STM32CubeIDE, C/C++ and Python. I focus on understanding the requirements first, then creating an organized design, checking the result carefully and delivering files that are practical for prototyping or manufacturing.
