I specialize in hardware design, embedded systems architecture, and professional PCB layout. My primary focus is translating system requirements into reliable, manufacturable, and industrial-grade hardware. While my core day-to-day work involves embedded hardware and robust PCB design, I also have a solid background in high-speed digital design principles. I approach every board with strict attention to Signal and Power Integrity, EMI/EMC mitigation, and Design for Manufacturing (DFM). Core Capabilities: Embedded Hardware Design: Designing solid hardware architectures around microcontrollers (STM32, ESP32, AVR), including power regulation systems, communication interfaces, and sensor integration. PCB Layout & DFM: Expertise in designing multi-layer boards using Altium Designer. I design strictly for the factory floor, adhering to IPC-2221/IPC-7351 standards to ensure your design is fabricated and assembled without technical hold-ups at houses like JLC or PCBWay. High-Speed & Mixed-Signal: Capable of handling complex constraints when a project demands it, including impedance matching, length tuning, and differential pair routing for FPGAs and memory interfaces (DDR). Power & Analog Electronics: Experience with switching regulators (SMPS), high-current drivers, and low-noise analog front-ends.

If you are looking for a practical, detail-oriented hardware engineer who speaks the language of datasheets and delivers ready-to-manufacture designs, let's discuss your project.

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.
