I specialize in end-to-end hardware product development, from initial concept and schematic design to PCB layout, prototyping, and manufacturing support. I have worked with startups, small businesses, and independent inventors to transform ideas into fully functional, production-ready devices. Key Responsibilities: Designed single-layer, multi-layer, and high-speed PCBs using Altium Designer, KiCad, and Eagle Created detailed schematics, BOMs, and manufacturing files (Gerber, Pick & Place, Drill files) Developed embedded systems using microcontrollers such as ESP32, STM32, and Arduino Built and tested prototypes, identifying and resolving hardware issues efficiently Designed 3D enclosures and product casings using SolidWorks and Fusion 360 Prepared designs for mass production, including DFM (Design for Manufacturing) optimization Collaborated directly with PCB manufacturers and assembly houses to ensure accurate production Provided technical documentation and post-delivery support to clients Key Projects & Achievements: Designed a custom IoT-based control board with wireless connectivity (WiFi/Bluetooth), successfully deployed for prototype testing and production Developed a multi-layer PCB for a consumer electronic device, reducing noise and improving performance stability Created a complete product enclosure with optimized thermal management and manufacturability Assisted multiple clients in transitioning from prototype stage to small-batch and mass production Reduced production costs by optimizing component selection and PCB layout efficiency Tools & Technologies: Altium Designer, KiCad, Eagle CAD SolidWorks, Fusion 360 Arduino IDE, PlatformIO Oscilloscope, Multimeter, Logic Analyzer ESP32, STM32, Raspberry Pi
