Hire the Best Circuit Designers in California

I am an applied PhD (Berkeley EECS) scientist with 10+ year industry experience in solving robotics, signal processing, and embedded system problems. I have over 20 years experience working with electronics and embedded systems. I have built entire robotics systems from the ground up (e.g. a car-carrying AGV) as well as led software component development as part of a larger effort (e.g. developed next-gen Fitbit heart rate algorithm). Achieving a certain product or customer outcome requires a high-level systematic viewpoint- I can help break-down this outcome into achievable and straight-forward sub-goals. From there, whether the solution calls for a data-crunching python script or bare-metal C coding, I can bring whatever tools are needed and use them with mastery. We are now bringing world-class talent together to push technological progress at Think Circuits LLC, where I am CEO. Here are some problems I can solve for you: * New algorithm development- Set requirements, design, implement and validate. * Improving legacy algorithms - Determine weaknesses of an existing algorithm, determine high-value improvements, implement and regression testing to track gains. * Embedded circuits design - Design and fabricate special purpose electronics such as sensor data loggers or controllers. * Research- Pursue a research direction such as applying a research paper to a given problem, report on feasibility What skills are in my "wheelhouse" of tools? * Robotic localization and mapping (SLAM) : Graph-based and filter-based * Classic Estimation and control: Kalman filtering, full-state controllers/estimators, PID control * Signal processing : Frequency and time domain analysis, PCA, adaptive filtering and regression * Classic machine learning : SVM, Random forest, polynomial regression * Regression testing scripts and statistical analysis of performance * Fluent in C,C++, Python * Experience with Javascript, Typescript, Linux * Embedded circuit design What will working with me be like? For development or research work, I will first try to understand the problem you are trying to solve and determine whether it is within my area of expertise. If I am able to help, I will propose some directions or options. If possible, we can identify the interfaces which separate my work from the rest of the project and come up with requirements definitions on those interfaces. Then, I can be fairly self-sufficient to implement the outcome. Other times, the desired outcome is less clear and so a more "agile" approach can be taken with greater back-and-forth between us.

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.

Hello! I am an ambitious Aerospace Engineer who leads by example and strives for perfection. My strengths are mechanical design (CAD), structural analysis (FEM), fluid mechanics and thermodynamics. I can quickly iterate on prototypes and I enjoy bringing ideas from concept to fruition. I enjoy working on aerospace vehicles, mechanical systems, deployable structures, and racecars. My expertise is in conceptual and detail design and analysis of metallic and composite structures, mechanisms, and pressurized fluid systems. I have worked on the rockets at SpaceX, the spaceships at Virgin Galactic, the satellites at SpinLaunch, and electric aircraft at Lilium Aviation. I am a collaborative team player and look forward to working together if there's something I can help with!

For 7 years, I’ve helped eCommerce brands turn their products into their #1 sales asset, not just content that looks good, but visuals that drive clicks, build trust, and close sales. As the Founder and Creative Director of YKC Studio, I don’t just deliver files, I deliver a complete visual strategy. I combine product photography, 3D modeling, and video advertising into one cohesive system built around one goal: your conversion rate. One of my Amazon clients updated their main listing images with our studio work and saw a 35%+ increase in click-through rate within the 2 months. That’s the difference between visuals made for aesthetics and visuals made for performance. I work with brands selling on Amazon, Shopify, and running paid ads on Meta and TikTok , and I approach every project knowing that your visuals are competing in a feed or a search result where you have less than 3 seconds to stop the scroll. My process is end-to-end: creative direction, styling, shooting or rendering, retouching, animation, and final delivery formatted for every platform you need. You don’t manage five different vendors, you work with one strategic partner who owns the outcome. If you’re ready to stop blending in and start winning the visual game, message me with your product and I’ll tell you exactly how I’d approach it. What I Deliver — and Why It Works: ▪ Amazon Listing Photography — hero images and infographics engineered to win the click and reduce returns ▪ 3D Renders & Product Animation — photorealistic visuals without the need for physical samples, perfect for launches and mockups ▪ Video Ads for Meta, TikTok & YouTube — short-form content built around platform-native psychology and buying behavior ▪ Motion Graphics & Brand Identity Content — scroll-stopping motion that builds brand recall across every touchpoint ▪ End-to-End Creative Direction — one strategic partner managing the full visual production pipeline so your brand stays consistent at scale
