Hi, I am an embedded systems engineer with over 16 years of experience developing consumer electronics from concept through production, including circuit and PCB design, Arduino/ESP32 firmware, simulation, bring-up, testing, and troubleshooting. I can turn your requirements into a practical hardware and firmware solution, then provide the schematics, source code, PCB and Proteus files where needed, BOM, and clear technical documentation. My relevant work includes ESP32-connected devices, custom microcontroller boards, sensor and control systems, and production-ready PCB designs. Much of this work is private and cannot be shared publicly, but I can show suitable examples privately. Once I review the exact application, interfaces, power requirements, and expected operating conditions, I can propose the architecture and confirm milestones. What is the first device or system you would like to develop? I would be happy to discuss the details and recommend the best approach.

Hi, This is a very good match for my background. I have 10+ years of hands-on experience in electronics, embedded systems, PCB design, Arduino/ESP32, STM32, firmware, and troubleshooting. I can handle projects from circuit concept → schematic → simulation → PCB → firmware → testing, rather than working on only one part of the system. I’m experienced with KiCad, Altium, Proteus, C/C++, ESP32, Arduino, STM32, sensors, IoT, UART/I²C/SPI/CAN/RS485, and various hardware interfaces. I can provide complete source files, BOM, firmware, simulation files, documentation, and testing support. If you have an upcoming project, send me the requirements and I’ll suggest the most practical architecture and development approach.

Hi, We at HardFault can support the complete electronics and embedded development cycle, from understanding your requirements and designing the circuit to firmware development, PCB design, simulation, testing, and troubleshooting. Our experience covers Arduino, ESP32, STM32 and other microcontrollers, along with sensor interfacing, communication protocols, power electronics, schematic/PCB design, and embedded firmware. We can provide clean schematics, production-ready PCB files, Proteus simulations where required, well-structured source code, BOM/component selection, testing support, and clear technical documentation. Rather than treating hardware and firmware separately, we focus on making the complete system work reliably together and can also troubleshoot or improve an existing prototype if needed. As a team, we can handle different parts of the project in parallel, which gives you better technical coverage and faster progress than relying on a single individual. We are also comfortable adapting to project-specific requirements and can share relevant examples of our previous electronics, ESP32, Arduino, PCB, and embedded systems work. Could you share the first project or existing prototype you would like us to review so we can suggest the most efficient hardware and firmware approach?
