I’m an Embedded Systems Engineer specializing in building reliable, production-ready embedded systems and IoT devices. I work across both firmware and hardware, helping clients turn ideas into fully functional, manufacturable products. My work covers the full embedded stack from circuit design and PCB layout to firmware development and system integration. I focus on building systems that are not just functional, but stable, efficient, and ready for real-world deployment. I’ve worked with startups and engineering teams on everything from early-stage prototypes to production-level embedded systems using ESP32, STM32, and nRF platforms.

Firmware Development: nRF52840, nRF52832, nRF52, nRF51, STM32, ESP32, PIC16, PIC18, ARM, MSP430, stellaris, LPC, Atmel, Cypress, Renesas, Arduino etc. I have Experienced with BLE, WIFI, I2C, SPI, UART, Ethernet using micro controller. Android and iOS Application development.

Reliable firmware is not only about writing code, it is about understanding how the device behaves when hardware, timing, memory, and communication all meet in the real world. My background covers C, C#, C++, Linux, firmware development, microcontrollers, Embedded Linux, RTOS, sensors, device drivers, and hardware level debugging. I have handled systems where the first version seemed functional, but problems appeared during long operation, unstable communication, incorrect startup behavior, or inconsistent sensor data. In those cases, I focus on finding the real cause instead of adding quick patches that create more issues later. I can develop firmware from the beginning, improve existing code, bring up new boards, connect peripherals, debug low level communication, and prepare embedded devices for more stable use. My experience includes UART, SPI, I2C, CAN, MQTT, Linux based device software, hardware control logic, and testing directly on real boards. I care about clean structure, readable code, practical debugging, and making sure the software can be maintained after the prototype stage. The goal is always the same: a device that starts correctly, communicates reliably, handles errors properly, and keeps working when it is used outside of a simple test setup.

Helping Medical Device & Industrial Companies Rescue and Accelerate Embedded Product Development | Embedded Firmware + Hardware | 40 Years Experience. Embedded systems become difficult when firmware, hardware, communications, and real-world physics all intersect. That's where I do my best work. For nearly 40 years, I've helped companies develop reliable embedded products—from concept through production—for medical devices, industrial controls, transportation systems, and connected IoT products. Whether joining an existing engineering team or taking ownership of a complete subsystem, I focus on building solutions that are reliable, maintainable, and ready for the real world. Unlike many embedded consultants, I bring expertise in both embedded firmware and electronic hardware design. That allows me to solve problems at the system level rather than treating firmware and electronics as separate disciplines. Many of the most challenging bugs and design issues live at the boundary between the two.
