I specialize in embedded firmware and PCB development for IoT, industrial automation, wireless devices, and microcontroller-based products, as well as software development. I help startups, product teams, and hardware companies build reliable embedded firmware and PCB solutions for real-world products, along with software Development. My core work includes STM32, ESP32, Arduino, FreeRTOS, Modbus, RS485, CAN, BLE, Wi-Fi, MQTT, IoT gateways, sensor integration, PCB schematic/layout review, and firmware debugging. I can work on both sides of an embedded product: firmware and hardware. Clients usually hire me when they need help with: ✅ Firmware development for STM32, ESP32, Arduino, PIC, AVR, and nRF52 ✅ Debugging unstable firmware, communication issues, sensor errors, and hardware faults ✅ Modbus RTU/TCP, RS485, UART, SPI, I2C, CAN, BLE, Wi-Fi, MQTT, HTTP, TCP/IP ✅ PCB schematic review, multilayer PCB layout, Altium/KiCad/EasyEDA support ✅ IoT device development from prototype to working product ✅ Hardware bring-up, testing, documentation, and production-ready fixes ✅ Software and Dashboard Development (Python, NodeJs etc) What makes my work different is that I do not only “write code.” I analyze the full system: schematic, power, PCB layout, firmware architecture, communication timing, logs, and real hardware behavior. This helps find the actual root cause instead of only applying temporary fixes. My workflow is simple: Review your requirements, schematic, code, logs, and hardware setup Identify risks, missing details, and possible failure points Build or fix the firmware/hardware step by step Provide tested code, clear documentation, wiring diagrams, and handover files I have worked on embedded systems involving industrial controllers, IoT devices, wireless communication, custom PCBs, automation systems, sensor-based devices, and microcontroller firmware. If you need an embedded engineer who can understand both firmware and hardware, communicate clearly, and help move your product forward, I can help. Send me your project details, schematic, code, or issue description, and I’ll suggest the best practical next step.
