PROFILE
Ahmed Ahmed
Worked on Bluetooth stack enhancements and UART driver reliability within the Zephyr ecosystem, contributing to both the telink-semi/zephyr and nxp-upstream/zephyr repositories. Improved Bluetooth host transmission scheduling by iterating through all available connections to prevent starvation and manage buffer constraints, while also addressing connection handling reliability and memory safety using C and embedded systems expertise. In a separate effort, fixed a critical baudrate calculation bug in the nrfx_uarte driver for nRF54x devices, aligning the macro with datasheet specifications to reduce errors in high-speed UART communication. Demonstrated attention to code safety, documentation, and adherence to Zephyr contribution workflows.
