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.

I have good experience of three years of teaching Circuit Theory and Basic electronic Devices such as Diode, MOSFET, BJT, Op-Amp, Differential pair, Current Mirror, and Oscillator topics such as Harmonic oscillator and multivibrator. Also related topics such that Feedback, frequency response, and noise analysis. I have good experience in cad tools such that Altium, protus, Multisim, OR CAD, and LT spice. I graduated from the department of communication and electronics and Mastered analog and Digital (Mixed) IC circuits and Master Cadence Virtuoso software and VLSI Layout. I also Work on Matlab, Simulink, and Matlab GUI. I design a high-speed current steering Digital to analog converter in cadence virtuoso and its related circuit like Decoder, Flip Flops, and Applying Dynamic Element Matching to our DAC by using a Logarithmic shifter and 16 Bits linear feedback shift register and dealing with designing a custom Digital logic gates and Layout for each one. Also, a two-stage biopotential amplifier for ECG, EMG, and EMG applications is performed in 130 nm technology under Cadence Virtuoso. all of my previous give me a good experience
