    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.

    For the past 20 years, I have been engaged in the design and production of electronic devices, including wireless devices. During this period, I started with antenna design, designing and producing FMCW radar in each frequency band (including millimeter waves), and continued until the signal processing unit section. In addition, a wireless direction finding system with high measurement accuracy was developed based on phase interference correlation processing method, and a coordinate measurement system combining TDOA and GPSDO was developed. The operating frequency bands of these two systems are between 20 MHz and 6 GHz. In addition, he also developed a radar frequency band signal analysis and directional analysis system based on IFM and BM methods. The frequency range of this system is 2 to 18 GHz. Moreover, while developing wireless navigation devices that can perform GPS RTK and Heading, a precision inertial navigation system has also been completed. This heading is based on a GPS system and is not affected by surrounding algae. Moreover, with the advancement of high-speed PCB design for RF systems, high-speed signal processing circuits above 1GHz and various Android, Linux devices, etc. have been widely introduced into a field. The programs used in these processes include: - RF simulation and design program: CST Studio, ADS - PCB design program: Altium Designer. - Mechanical design program: Solidworks. - Signal processing programs: ISE, Quartus, Keil, MPLAB X, Arduino. Matlab, And developed intelligent lock with facial recognition and fingerprint recognition functions, and has sufficient experience in mass production, establishing a monthly production process of more than 10000. In this process, a procurement process for various elements, including RF elements, and a production and testing process for components have been established. Regardless of the type of product or the quantity, there is rich experience in overseas direct delivery. And, I can process various sourcing and delivery of various electronic components.

    Professional Firmware and IoT Developer. I have five years of experience in the development of IoT Projects. My focus is on long-term clients. I have managed to help develop and grow a few businesses in the IoT, Projects with more than three hundred customers. Strong experience on Unit Test and CLI tools for firmware development, also a good old Git terminal user ( I never got used to UI Git software) Frameworks: PlatformIO, Arduino, ESP-IDF, AngularJS, NodeJS. Development Boards: Arduino, Espressif (8266. and esp32), Particle (Electron and BSoM, NRF52, Seed). Communication Protocols: WiFI, HTTP/S, MQTT, SPI, I2S, I2C, BLE. Internet of Things: RestFul API's, AWS IoT, Quectel Boards (AT commands), HomeAssistent, and NodeRed. Languages: Python, JavaScript, c/c++ (mostly 11 and for embedded systems, but it is the language of choice). Dashboards: Strong knowledge of Maintenance, development of rules and widgets on ThingsBoard, and also Thingsboard Version Updates (if you ever had to do one, you already know why I'm putting it here). Familiar with: Docker, Docker-compose, Swagger, Postman, and Linux system automation using python. Side Notes: OS of choice is a macOS and a Unix-based terminal is my second home. I use Vim style in my browser and OS, Capslock was never once used as intended.

    I'm a programmer, PCB designer and scientist in our Ultimate Robotics team (we develop prototypes in wearables, sensors and robotics). I specialize in PCB design, writing firmware and creating custom optimized algorithms. Microcontroller programming: — nRF52x, ESP32, STM32Fx/Lx/Gx, Atmega328P/Arduino, ATtiny. Implemented BLE protocol from core specification in order to remove dependency on Nordic softdevice. Wrote drivers for multiple devices (ADCs, IMUs, RF chips and others). Mathematics and algorithms: — IMU processing - quaternion based position integration, fusion of several data sources, analysis of sensor mesh — signal processing, FFT for microcontrollers/SoC/PC with realtime graphical display output — PID control, vector BLDC control — Computer Vision algorithms, especially highly optimized to run on systems with low computational capabilities — Machine Learning, especially neural networks - wrote several papers on new methods in the field, published in high quality peer reviewed journals PCB design/Gerbers for 2/4 layers boards (usually takes from 2 hours to 2-3 days): — sensitive, low noise analog front ends — onboard signal processing (it's best to filter realtime raw data) — single or multiple processors (why not, even Arduino has two) — wireless and RF: BLE, RFID, WiFi and custom RF links — LED matrices, screens, touch/proximity/ordinary buttons C programming on Linux: Often you can't fully utilize hardware system without a PC interface, and Linux with C program is the most efficient choice in this case.
