    Good working day! I'm here to provide systems work, live, update, and development. I want all the products I develop see the light of day, sell successfully, and become better for users and owners. If you ask me what is the meaning of life, I'll answer – in programming. So, my job is programming, my hobby too. By the way, if you need a first-class programmer – I'm here. I’ve been providing excellent firmware development services for over 10 years. It confirms my status 100 % TOP rated + on Upwork. Perfectly functioning devices and satisfied customers will speak better for me. Do you want to save your time on pointless meetings where engineers ask you what to do instead of doing it? Do you want to increase your income through our productive cooperation? Do you want a perfect, functioning, advanced product that you and your customers will like? I'll help you find a solution for your problems as soon as possible to implement them at a high level. The main goal is to help you achieve great success and make results. The most important thing is the product. It will be innovative, progressive, fresh, and efficient. I'll develop firmware, support it, and add new features, thus improving the product and the owner's profit. I'm always open to communication and find it useful. The more feedback I receive from you, the more I'll give you in return. Then I would like to tell you exactly how the cooperation goes. And now you can look at reviews of my work left by my clients on Upwork. I want you to understand the most important benefits that I can provide you are time and freedom. I can independently make decisions without disturbing the customer. You can go about your business while your project is running. At the same time, I work on technical tasks and take responsibility for my actions. So, I offer long-term cooperation which means the full cycle of device development and support. Please note that the latest versions are released as soon as new features are added. Every next release brings us closer to the final version of the device. Eventually, I would like to give you a guarantee. Guarantee of 100% satisfaction with the result. Unfortunately, my resources are limited, so I don't take on many projects. If you have a clear understanding and vision of your project and want to start right now, just write to me. Let's talk, discuss, make a plan and grow your business. If you still have doubts about something, then I have a consultation service – where we’ll analyze all the issues together that will help you see the future of your project, understand the next steps, and possibly start our cooperation.

    I have over 22 years of experience working and consulting for tech companies in Silicon Valley. Every technical challenge that I had overcome assured me that with the right frame of mind, I could accomplish anything. Engineering is also my hobby, and I have been doing it since before high school. I was born with a soldering iron in one hand and writing code with the other. I designed the hardware for over 100 projects, most of them being sold today. Some notable ones are Snapchat Spectacles (designed most of the electronics and PCB layout), Thornwave Labs' Bluetooth DC Power Meter (PowerMon) and all the other projects on the webpage, various RF modules (RN-171, RN4020, RN52), and development boards designed while working at Microchip. I also created production testers, lots of C/C++ programming, and firmware design. What I can do for you? --------------------------- High Level: project management, research. I am very experienced with hardware design and firmware, which allows me to integrate them more efficiently. Hardware: circuit design, component selection, electrical schematic, PCB payout. I am using Altium Designer. I will provide you with everything you need to go to manufacturing: Gerber files, NC drill, pick and place, assembly diagrams, 3D prints, 3D STEP model, and electrical schematics as well as offer support after the project is completed. I have experience with analog and digital design, RF, high-speed design, microcontrollers, highly complex boards, LCDs. I can run Spice simulations as well. I worked with various technologies and protocols: SPI, I2C, UART, USB, CAN, RS-485, Ethernet, Bluetooth, WiFi, and so on. Prototyping: I will manufacture the prototypes at a much lower cost than average. Over the years, I have developed working relationships with manufacturers in China, hence the cost-saving. I also have a lot of equipment: multimeters, oscilloscope, logic analyzer, vector network analyzer, USB protocol analyzer, power supplies, digital electronic load, soldering equipment, computers, and so on... Certifications: I can assist and oversee the certification process for FCC, IC, and others. Firmware development: I have 24+ years of experience coding in C/C++ and 20 years of firmware development. I can architect and develop your firmware from the ground up. I am exceptionally versed in the ARM Cortex line of microcontrollers: STM32 and Nordic. I will provide you with production-quality firmware. I know the ST and the Nordic microcontrollers like the back of my hand. I can get firmware done very quickly and efficiently for these chips. Software development: Basic tools running in Linux/Windows/Mac, basic GUIs. I can develop all the software tools you need for debugging, testing, and manufacturing. Manufacturing: If your project reaches this phase, I can offer contract manufacturing services. I will be delivering your finished product, ready to sell. The rate I displayed is an average number. It can vary up or down based on the complexity of the project. My rate reflects the experience and knowledge I have. I am good at what I do. Also, keep in mind that I will not bill you for hours like lawyers do for the time they spend in the shower thinking about the project. I will bill you only for the hours I spend advancing the project in a meaningful way.

    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.
