Transforming complex hardware requirements into robust, market-ready products. I am a Senior Electronics and Hardware Design Engineer specializing in multi-layer PCB layout, mixed-signal routing, and power electronics. I take a rigorous, Top-Down Design approach to hardware development, ensuring that your prototype doesn't just work on a breadboard—it survives EMC testing and is strictly optimized for mass manufacturing (DFM/DFA). Whether you are building a high-frequency RF DAQ board, an industrial IoT sensor node, or a custom motor driver, my focus is on signal integrity, power stability, and first-spin success. Core Engineering Competencies: PCB Design & Layout: High-speed digital, analog, and mixed-signal boards (Altium Designer, KiCad). Controlled impedance, meticulous return-path analysis, and strict EMC/EMI mitigation. Power Architecture: Transient load handling, split-rail isolation, SMPS, and Battery Management Systems (BMS) for edge devices. Embedded Hardware: Deep expertise in architecting reliable hardware, ESP32/ESP32-S3, and similar MCU ecosystems. RF & Antenna: Microstrip antenna simulation and optimization using HFSS. Validation & Benchmarking: Comprehensive circuit analysis, competitive tear-downs, and in-house physical prototype validation. My Development Sequence: Architecture & Calculation: Pre-layout simulation of critical blocks, thermal management, and transient load mitigation. Schematic Capture & PCB Layout: Clean, hierarchical schematics and precisely routed multi-layer boards. Manufacturing Handoff: Generating flawless, factory-ready production files (Gerbers, NC Drill, Pick-and-Place, and optimized BOMs) for seamless assembly at houses like PCBWay or JLCPCB. I believe in absolute engineering honesty. If an architecture is physically flawed or a requirement risks your power budget, I will flag it upfront and engineer a reliable alternative. Send me a message with your project brief or NDA, and let's discuss how we can bring your hardware to life.
