Hi, Welcome! I’m an Electronics Engineer with expertise in hardware and PCB design, specializing in signal integrity (SI), power integrity (PI), EMI testing, and power distribution network (PDN) analysis. I have extensive experience in both analog and digital IC design using Cadence tools and various open-source platforms. Additionally, I work with FPGAs using Vivado, ISE, and ModelSim. Hardware and PCB design is my passion, and I have collaborated with multiple companies to create custom embedded board designs, including SoC, memory interfaces (LPDDR4, DDR4, DDR3), HDMI, Ethernet, and PCIe protocols. Struggling with signal integrity, EMI, or power delivery issues in your PCB or IC design? I specialize in fixing high-speed design problems like crosstalk, reflections, and EMI/EMC failures. Whether its a DDR memory interface, USB/PCIe signal degradation, or noisy power distribution network (PDN), Ill analyze your design and provide clear solutions. Using industry tools (HyperLynx, ADS,), I optimize impedance matching, termination schemes, grounding strategies, and decoupling networks to ensure robust performance in PCB schematic and layout aand Analog IC layout. Need pre-compliance EMI testing help? Ive got you covered. Signal Integrity (SI): Fix reflections, overshoot, and timing issues. EMI/EMC Reduction: Identify and suppress noise sources. PDN Optimization: Stabilize power delivery with decoupling analysis. Crosstalk Mitigation: Minimize interference in dense layouts. Lets make your design reliable and compliantmessage me before ordering to discuss your project

I’m an Electronics & Electrical Engineer specializing in PCB design, circuit engineering, embedded systems, RF hardware, power electronics, simulation, and electronics reverse engineering. I help startups, engineering teams, researchers, and product developers turn ideas, prototypes, and existing hardware into reliable, manufacturable, production-ready electronic products. I work across the complete hardware development cycle, from system architecture and circuit analysis to schematic design, PCB layout, prototyping, testing, debugging, firmware integration, and manufacturing preparation. 🔧 PCB & Electronics Hardware I design professional 2–16+ layer PCBs for analog, digital, mixed-signal, high-speed, RF, and power applications. • Schematic and circuit design • High-speed & controlled-impedance PCB layout • RF PCB layout and PCB trace antenna design • Power & signal integrity • EMI/EMC-aware design • DFM/DFA/DFT optimization • Component selection and BOM optimization • Gerber, NC Drill & Pick-and-Place/CPL generation • PCB review, debugging and validation • Manufacturing-ready documentation Tools: Altium Designer, KiCad, EasyEDA, Proteus 🔍 PCB & Electronics Reverse Engineering I can reconstruct and analyze existing electronic hardware from physical PCBs, photographs, Gerbers, legacy schematics, and prototypes. This includes component and IC identification, net tracing, schematic reconstruction, PCB layout reconstruction, BOM development, connector/pinout analysis, datasheet research, functional block identification, design verification, and preparation for manufacturing or modification. The goal is to understand the original design electrically and create a structured, usable engineering design rather than simply copying the board. 💻 Embedded Systems & Firmware I develop and integrate hardware with: STM32 • ESP32 • ESP32-S3/C3 • Nordic nRF52/nRF53 • AVR • PIC My embedded work includes Embedded C/C++, Bare-Metal, FreeRTOS, drivers, bootloaders, sensor integration, peripheral configuration, and hardware–firmware debugging. Protocols: UART, SPI, I²C, CAN/CAN FD, USB, Ethernet, BLE, Wi-Fi, LoRa, MQTT, RS-232, RS-485 and Modbus. 📡 RF & Antenna Engineering I work on RF PCB layout, controlled-impedance routing, wireless hardware, antenna integration, and PCB trace antenna design. I also use CST Studio Suite for antenna modeling and analysis. My experience includes BLE, Wi-Fi, LoRa, LTE/5G and other wireless electronic systems. ⚙️ Power Electronics My power-electronics experience includes AC-DC/DC-DC converters, battery charging and protection, BMS-related circuits, power management, motor controllers, high-current electronics, protection circuits, renewable-energy systems and inverter-related hardware. I consider component ratings, thermal performance, current paths, switching behavior, grounding, protection and PCB layout during development. 🧪 Simulation & Validation I use simulation and analysis to identify design problems before hardware fabrication and reduce unnecessary prototype iterations. Tools: LTspice, PSpice, MATLAB/Simulink, PLECS, Multisim, Proteus and CST Studio Suite. 🏭 Product Development & Manufacturing I can support your product from: Requirements → Architecture → Circuit Design → Schematic → PCB → Simulation → Prototype → Firmware → Testing → DFM → Manufacturing Deliverables can include schematics, PCB source files, BOM, Gerbers, NC Drill files, Pick-and-Place/CPL, assembly documentation, 3D models, firmware files and manufacturing documentation. I can also review existing manufacturing files for incorrect footprints, missing files, component availability, BOM issues, fabrication/assembly problems and DFM requirements. Why Work With Me? ✔ Professional PCB & electronics engineering ✔ Advanced Altium & KiCad experience ✔ Analog, digital & mixed-signal expertise ✔ High-speed and RF PCB design ✔ Embedded hardware–firmware integration ✔ PCB/electronics reverse engineering ✔ Simulation-driven development ✔ Power electronics experience ✔ Manufacturing-focused designs ✔ Clear technical documentation and communication Whether you are developing a new electronic product, improving an existing PCB, reproducing legacy hardware, integrating embedded firmware, or preparing a design for manufacturing, I can help take the project from its current stage to a reliable and practical engineering solution. Send me your schematic, PCB files, Gerbers, BOM, photographs, prototype details, or project requirements, and I’ll recommend the most suitable engineering approach.

I design hardware that ships, PCB-based systems built around ESP32, STM32, Nordic nRF, and NXP i.MX, taken from a blank schematic to a manufacturable, field-ready product. My focus is the intersection of power integrity, signal integrity, and EMC: designing boards that pass compliance, survive real-world conditions, and scale from 10 to 10,000 units without layout surprises. I've shipped power delivery systems (USB-C PD, isolated flyback AC/DC, multi-rail industrial supplies), DSP control boards for 3-phase inverters built around the TI TMS320F28377, and connected IoT products combining STM32, ESP32, and industrial-grade mixed-signal layouts. My designs include 6-layer PDN-optimized boards, 24V industrial sensor systems with isolated RS485, and wireless platforms using pre-certified BLE modules. Every design I deliver includes: schematic + layout in Altium Designer or KiCad, LTspice simulation for power stages, production-ready Gerbers, BOM with alternates, and manufacturing notes. I test with oscilloscopes and logic analyzers before anything goes to fab. If your hardware needs to be reliable in the field, not just on the bench, let's talk about your project.

I design and build real hardware systems, not just firmware. I’m an electronics engineer with 3+ years of hands-on experience in embedded systems, PCB design, and full hardware integration, with over 80 completed projects across IoT, wearables, RF systems, and high-performance embedded platforms. I work on projects where hardware actually has to function in the real world, dealing with power, noise, thermals, wireless reliability, and system-level integration.

Will signals behave correctly (not just in theory)? Will manufacturing and assembly go smoothly? Can this scale beyond the prototype? That’s the level I work at. If you’re building something that needs to actually work in hardware, I can help you get there.
