During my previous role as an Embedded Systems Engineer, I was responsible for designing and developing low-power embedded devices from concept to production. Key achievements and responsibilities included: • Designed and developed low-power electronic circuits using microcontrollers such as ESP32, STM32, and Nordic nRF series. • Created complete hardware designs including schematics, component selection, and PCB layouts optimized for reliability and power efficiency. • Developed and maintained firmware for embedded systems, including sensor interfacing, communication protocols (I2C, SPI, UART), and wireless connectivity. • Integrated wireless technologies such as Wi-Fi and Bluetooth for IoT-based applications. • Performed hardware debugging, firmware testing, and system-level troubleshooting to ensure stable and efficient device operation. • Worked closely with manufacturing teams to prepare designs for production, including prototype testing, design validation, and production optimization. • Successfully contributed to multiple products that moved from prototype to full production and are currently being sold in the market. This experience allowed me to gain strong expertise in developing reliable embedded systems, optimizing power consumption, and delivering production-ready hardware and firmware solutions.

Usman was wonderful to work with, i asked him and his team to engineer the entire project. He delivered in a short time and made a clean product. The communication was excellent, and Usman is more than willing to continue with the next stage of the project.

He took the time to walk us through all the PCB-related topics in detail, answered all of our questions, and made even the more complex aspects easy to understand. His knowledge, professionalism, and clear communication made the session...
