    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.

    🏆 Top Rated Product Developer ( I've developed my own products || I'm now helping others on the Upwork platform ) 🏠 I have a Small Home Laboratory to develop/debug prototype boards for your product 💭 I'm a native English speaker My name is Stephen, and I have 25+ years in product development, including 13 years at Microchip in roles like Test Engineer, Design Engineer, Silicon Validation, and Applications Engineer. I specialize in developing products from concept to working systems. I can handle both hardware and software or work flexibly on specific areas like architecture and hardware design. I’ve developed two successful products: (1) KEYKatcher hardware keylogger – A device plugged into a PS/2 keyboard port to record and play keystrokes. It was popular among parents for monitoring children's computer use, with tens of thousands sold. Sales declined as PS/2 ports became obsolete (2) TightWatt pool timer – An intelligent controller for swimming pool motors, featuring a year-round algorithm. It was awarded a patent and gained national distribution. Through all the product development, I’ve created a system for planning and designing working products. This system reduces costs ( by reducing mistakes ). I frequently make product improvements in 1️⃣ Lowering energy usage: important in battery-powered products 2️⃣ Increasing performance: increasing sample rates or changing communications protocols 3️⃣ Lowering product cost: making full use of the microcontroller peripherals to reduce external components I have completed more than 70 projects on Upwork but to check my capabilities or skills, you can check out the following projects: ➡️ Hardware Prototype Design for Plant Monitor Product using ESP-32 ➡️ Microchip ATtiny202 Code Development ➡️ Energy Storage Monitoring System ➡️ BM83 Bluetooth Application Schematic ➡️ Embedded System with PIC Microcontroller & Accelerometer ➡️ PCB Power Usage Optimization ➡️ TI MSP430 Development Additional Skills: ➕ Leading-edge technologies such as USB/USB-C, Lithium Battery Charging, LED and Color Mixing, I2S Digital Audio, and Analog Measurements ➕ Common Communication Busses: USB, RS-232, RS-485, CAN, I2C, SPI, Infrared ( with carrier ) As mentioned above, I have a small home laboratory where I have all the tools I need to develop/debug prototype boards for your product. This includes: ⚙️ Multiple programmers for Microchip, Atmel, and TI parts ⚙️ Logic analyzers to quickly find issues with communication busses such as I2C, SPI, UART, I2S, …. ⚙️ A “power profiler” with picoAmp range ( yes, picoAmp, a trillionth of an Ampere ) for power optimization of low-power products ⚙️ A reflow oven for assembling prototype PCBs ⚙️ Inspection equipment for verifying PCB assembly ⚙️ A fellow Upwork contractor is available to do the physical assembly work. She works at a much lower rate than me and has the patience to hand-populate / hand-solder prototype boards Some electronic inventory is on hand. I may have all the components in-house to complete your project Feel free to contact me through UpWork. Best Regards, Stephen
