    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.

    Rapid system prototyping with off the shelf prototyping boards can be accomplished in a short period of time. I am familiar and have used prototyping and breakout boards from many companies including Arduino, Adafruit, Raytac, Microchip, Sparkfun, Nordic nRF52832 (BLE), Bosch (IMU), and others. When necessary, custom prototyping PCBs are created with PCB CAD tools I have excellent knowledge and experience in Software Development Life Cycle (SDLC) and Agile Methodologies. I am flexible to project demands and shifting technologies and requirements. Having a diverse background in embedded development, I can provide services based on years of experience with embedded systems in harsh user environments (cell phones, hobby grade R/C vehicles, sensors, and medical devices). Embedded technologies include concurrent use of pulse width modulation (PWM), analog to digital converters (ADC), digital to analog converters (DAC), Bluetooth LE (BLE), collection algorithms, control algorithms, motion sensing, temperature sensors, light sensors, and much more. I have a BS degree in Engineering with over 25 hours of graduate courses in CS at Johns Hopkins University. I have both designed and managed development of numerous embedded systems including voice (audio) systems for the US Air Force, Motorola Pagers, NEC cell phones, Samsung GSM/GPRS smart phones, and hobby grade (very advanced) radio control vehicles at Traxxas. At Traxxas, I provided hands on development and team management for all of the embedded hardware/firmware radio control technologies including spread spectrum radio control links, sensors (GPS, accelerometer, temperature, RPM, etc.), BLE link to iOS/Android phones with several awarded patents and additional patent applications still in process. Rapid development of a medical blue light sensor for an Upwork client connected to an Android App I also developed was completed in 4 weeks with a working prototype demonstratable to investors and end users. Development of a wearable 9DOF high precision motion sensor for an UpWork client illustrates my capabilities for embedded system development, PCB design, and embedded C programming. Thank you and I look forward to working with your company in the very near future. Best regards, Gary DeWitt

    1) RF System & mmWave I'm a RF engineer having more than 20+ years experience in the development and production of RF system and Antenna and other electronic device development. I have rich experiences in designing of RF system and programming of several MCUs and high performance FPGAs. I also used to design various wireless circuits such as the antenna, the power divider, the directional coupler and so on using RF simulation program such as CST and ADS. I have plenty of experience designing embedded devices using many types of micro-controller or wireless modules. In this period, I have used various sensors such as cameras and have experience in driving LCD display and LED matrix display devices, and also have experience in controlling motor and design of audio circuits. Some of these devices have the modules of Ethernet, Bluetooth, WiFi, zigbee, LoRA, GSM, NBIOT and so on. I am designing the devices using the Altium Designer, CST Studio, ADS, AutoCAD, Solidworks and so on. 2) Development of firmware For high efficiency and high reliability, I have used to develop my own firmware of the devices which I have designed by myself. I have used several applications such as Quartus (including ModelSIM), Keil IDE, IAR IDE, MPLAB X IDE, Atmel Studio, Arduino and ESP-IDF for the firmware's development. I have a wealth of experience writing an RTOS-based firmware. I also developed many firmware based on various communication protocols such as RS485, CAN, MQTT, TCP / IP and NB-IOT. Of course, many more modern IOT-related firmware using Bluetooth, WiFi, and zigbee have also been developed. 3) Product Sourcing Agent I have been involved in electronic product development for a long time, and I have full experiences of a comprehensive research, development and production from electronic product design to production completion. Of course, for marketed goods, I have also my own methodology to manage whole processes to ensure that our products have the competitiveness in the world market. Actually, I have enough experience in the previous company to produce the access controllers of more than 50,000 per month for more than 7 years.
