Hire the Best Circuit Designers in California

I am a Senior Hardware and PCB Engineer with 11 years of extensive experience in the complete hardware design cycle, specializing in defense-grade optoelectronic systems. I excel in creating detailed schematics and complex multilayer layouts for high-speed signals and FPGAs. My expertise in DFM, DFA, and DFT ensures seamless manufacturing processes while I act as the technical bridge between hardware designs and mechanical constraints. I am skilled in firmware-hardware integration and advanced lab validation, delivering solutions that meet stringent performance and reliability standards. If you need a proactive engineer who turns complex concepts into functional products, let's connect and discuss how I can elevate your project to the next level.

I am a “Jack of all trades” engineer with knowledge ranging from mechanical motion to pneumatic routing, power converters to bitwise logic, communication protocols to control systems modeling. I have worked in cross-disciplinary team settings and taken on individual projects where ownership and self-management is critical. My strengths include: - Mechanical modeling, analysis, and drafting - Design for manufacturing and assembly - Fluid routing and control - Rapid prototyping - PCB design and circuit prototyping - Sensor fusion and actuator control - Microcontroller programming - System modeling, simulation, and control - Communication protocols I have experience taking on projects that require knowledge in multiple realms of engineering, and translating that range of knowledge into completed products.

Hello! If you need an Electrical Hardware Design Engineer to take your idea and walking it through full cycle PCBA/System development from the proof of concept to fully functional prototype, that's me. I've been doing electronics work for the last couple of years, specifically rapid prototype development of tiny, wearable and battery operated devices, like earbuds, special purpose/medical watches, IoT and other devices required miniaturization efforts. I work with startups and understand stastups specifics - tight budget, fast turn-around times & a lot of uncertainty. I love what I'm doing: - Engineering Specification and Hardware Architecture Design; - BOM selection: low power consumption tiny MPUs and Audio DSPs (3.5mmx2.8mm with 0.35mm BGA pitch), small passives 01005 size, high efficient and battery operated switching regulators, tiny WiFi/BT chips and SoC; - Schematics Capture - experience with complex circuits and netlist, as small wearable; - PCB Layout for DFM - working with FAB houses in Asia and local to define high density layout rules, negotiating price and lead time the same time. I'm doing PCB Layout myself up to 8 layers and supervising CAD Team for more complex boards up to 32 layers - yes, I did it :-) Blind and laser via technics, power delivery planning, stackup definition, signal and power integrity rules, EMC/EMI. Tight component's placement and power noise decupling technics. Flex-rigid, flex and regular rigid boards from 0.11mm to 5.0mm thickness; - I have good sense of ME/PCBA integration in single device, worked closely with ME CAD Engineers and doing integration myself. My board's deliverables include 3D step file and all library. - Working on BOM procurement and kitting for proto build; - Working with FAB facilities to coordinate proto PCB fabrication - have direct local contacts and contacts in Asia - Working with PCBA facilities to assemble proto PCBAs - local and oversea; - PCBA's bring up, ME/PCBA integration, Firmware integration; - failure analisys and fixing issues; I'm working in the soul of Silicon Valley and have my own lab and tools to bring up prototype PCBAs, ME assembly/integration and firmware integration. Regular communication with my clients and vendors to sync and resolve technical issues as project management as well.

I started my journey in engineering during my university years, where my fascination with RF began. While others were exploring general electronics, I found myself deeply drawn to RF circuits, RF propagation, and RF system behavior. I spent countless hours in labs studying RF fundamentals, experimenting with RF signal generation, RF matching networks, and RF antenna design. My dream was clear early on, to become an expert in RF engineering and build real-world RF systems that solve complex communication challenges. During university, I focused heavily on RF projects, including RF transceivers, RF filters, and RF PCB design. I developed a strong foundation in RF theory, RF simulation tools, and RF measurement techniques using VNAs and spectrum analyzers. My academic projects revolved around RF optimization, RF impedance matching, and RF layout best practices, which shaped my career direction. After graduation, I transitioned into professional RF design, where I have been consistently working on RF systems, RF PCB layouts, and RF product development. My experience includes RF front-end design, RF antenna integration, RF shielding, and RF performance tuning for wireless systems such as WiFi, BLE, LoRa, and cellular IoT. I have hands-on experience in RF debugging, RF compliance considerations, and RF certification readiness (FCC/CE). My approach to RF design is practical and detail-oriented, ensuring RF signal integrity, minimizing RF losses, and optimizing RF performance in real-world environments. I continuously refine my RF skills through simulation, testing, and iteration, always aiming for high-efficiency RF solutions. Today, my goal remains the same as it was in university: to push the boundaries of RF design, create reliable RF systems, and deliver high-performance RF products that meet both technical and commercial requirements.
