Top Rated Plus Embedded Hardware & Firmware Engineer with 8+ 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.

I help startups, inventors, and businesses turn ideas into working embedded products, from concept and electronics design to PCB development, firmware, prototyping, and testing. I specialize in complete embedded product development, allowing clients to work with a single engineer instead of coordinating separate PCB designers, firmware developers, and hardware prototyping specialists. My expertise includes: • Embedded systems and firmware development (C/C++) • PCB design and layout (Altium Designer) • ESP32, ESP32-S3, STM32, Arduino, and PIC microcontrollers • Raspberry Pi 4, Raspberry Pi 5, Pico, and Pico W development • Sensor, motor, servo, and actuator integration • Hardware debugging, testing, and bring-up • IoT and connected device development • CAD support for enclosures and mechanical components Platforms & Technologies: • ESP32 / ESP32-S3 • STM32 • Raspberry Pi 4 / 5 • Raspberry Pi Pico / Pico W • Arduino • PIC Microcontrollers Protocols & Interfaces: • I2C • SPI • UART • CAN • I2S • USB OTG • USB-PD Recent projects include agricultural monitoring systems, robotics platforms, custom embedded electronics, and prototype product development. My focus is on practical engineering, clear communication, and delivering reliable prototypes that help clients move from concept to a working product faster.

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.
