-Integration of 5G SA/NSA on embedded Linux with HD video streaming

-Work closely with the hardware engineering team to do a schematic review, debug, integrate and fix the hardware.

-Work with Version control systems (git and GitLab) for code storage, projects integration, and issue tracking

- Analyze client/internal bugs, identify the root cause and resolve them with a minimum impact on the system.

- Design, implement and test a custom FOTA (Firmware Over The Air) over MQTT/HTTP and BLE 4.2 for wearable devices.

- Implement the communication with Amazone S3(HTTPS) and AWS IoT(MQTTS) on the embedded systems.

- Integrate and test secure BLE communication and BLE 5.0 on medical devices.

- Design and develop Android applications to upgrade the embedded systems via BLE 4.2 and to test the BLE 4.2/5.0 throughput.

- Integrating the Secure Boot and Secure Firmware Update(SBSFU) on the wearable IoT device.

- Customize the SBSFU to update the firmware over MQTT/HTTP.

- Write technical documentation and presentations on developed Software drivers and applications.

- Work with SVN for code storage and projects integration. Methodology: Agile/Scrum Languages: C/C++, Java, SQL IDE: Keil, Android studio, WICED studio, Eclipse, IAR Environments: Windows, Android

- Design and develop robust, flexible, reusable and optimized solutions for real-time embedded software systems.

- Test firmware which includes device drivers (I2C, SPI, UART, PWM,) and multitasking app code with demonstrated performance, reliability, maintainability.

- Design, implement and test a custom DFU (Device Firmware Update) OTA (Over The Air) via BLE 4.2 (Bluetooth Low Energy) with a smartphone.

- Design and develop Android applications to communicate, configure and upgrade the embedded systems via BLE 4.2.

- Integrate Firebase and Fabric cloud-hosted database to Android applications in order to allow real-time analysis, databases control and crash reporting.
