Top Rated Plus Embedded Hardware & Firmware Engineer with 15+ years of experience building reliable embedded products, IoT systems, and production-ready electronics. I help startups, product teams, and manufacturers take an idea, prototype, or broken design and turn it into a working embedded product that can be tested, manufactured, and scaled. My work connects hardware, firmware, and real-world product execution. Instead of treating the circuit, code, sensors, connectivity, power system, enclosure, and manufacturing process as separate pieces, I help bring them together into one reliable product. WHAT I BUILD • Custom schematic and PCB design for reliable embedded hardware • Embedded firmware development in C/C++ for real-world products • ESP32, STM32, Nordic, Arduino, Raspberry Pi, and Embedded Linux platforms • BLE, Wi-Fi, LTE, Cat-M1, NB-IoT, LoRa, NFC, GPS/GNSS, and sensor integration • Low-power electronics, battery-powered devices, BMS, and power management • Industrial interfaces including UART, SPI, I2C, RS-485, CAN, Modbus, ADC/DAC, and GPIO • Board bring-up, debugging, firmware validation, and hardware troubleshooting • BOM preparation, Gerber files, assembly files, DFM review, and manufacturing support I have worked across wireless IoT devices, wearable and medical electronics, industrial monitoring systems, automation hardware, smart sensors, connected consumer products, and custom embedded controllers. WHY ONE TECHNICAL OWNER Clients usually come to me when they need more than a schematic or a firmware file. They need someone who can understand the complete system, identify risks early, solve hardware and firmware integration issues, and move the product closer to production. I also lead a full-service engineering team when projects require additional support across mechanical enclosure design, cloud integration, mobile app development, product design, or manufacturing coordination. This gives clients one technical owner while keeping the embedded hardware and firmware work technically grounded. READY TO BUILD? Send me your requirements, target platform, connectivity needs, power constraints, current design files, and production volume. I’ll respond with a clear technical scope within 24 hours. Warm Regards, Huzaifa Ali

🏆 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. My clients communicate directly with me - I don't use any AI chatbots as intermediaries. 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
