🏆 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

With nearly 30 years of experience working across every IT platform, from MS-DOS, Novell Netware, Windows NT ... to every major platform on-premise and in the cloud today, there is not much I haven't worked with. I am a software developer who crossed over into hardware, then network engineering and administration. I work predominantly in cloud computing and datacentre’s space; this gives me the ability to understand how the software integrates into the hardware and network platforms very well. As CEO of my UpWork agency, vCloud Group - Global Cloud Services, I tend to work in all areas of Information Technology and Communications. Anything from desktop and workstations, to server systems, running Exchange, SQL Server, Oracle, Azure Integration, and system services like Disaster Recovery / Business Continuity, Multi-Site Cloud Networks and VoIP-based phone system. I am always working with my team to find the best possible solution for a client; I am not scared to advise you of a better solution that I believe you deserve or do better with. We have had several clients who started with one solution, then ended up with a better solution that exceeded their expectations. My experience has allowed me to work in areas: • IT systems and management, • technical support, and • project management. My focus areas on UpWork are: • Building of dedicated cloud networks in all major data centres, • VMWare vSphere/ESXi Hypervisor 5, 5.5, 6, 6.5, 6.7, 7.0, • VMWare vCenter 5.0, 6.0, 7.0, • VMWare Horizon View 4, 5, 6, 7, 8 all versions, • Microsoft Windows 10/11 all versions, • Microsoft Windows Server 2012/2016/2019/2022 all versions, • Linux all versions, • Dedicated Hosting Server i.e., cPanel/WHM, Plesk, CyberPanel, • Hosting Migrations from/to cPanel/WHM, Plesk or CyberPanel, • System Migrations, on-premise, cloud or hybrid (both), • Email Migrations (Google, Office 365 Migrations, and any to any), • VoIP Phone Systems, built-in any datacentre worldwide • All backup solution software on-premises or in the cloud. I am more than happy to discuss and look at projects first before accepting a contract; I ask many questions, and I double-check and follow up on everything I do. I hope to work with you soon.
