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 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.
