PROFILE
Lesley Rossouw
Lesley Rossouw worked on the au-ts/sddf repository, delivering a comprehensive overhaul of the I2C subsystem over two months. She refactored the I2C protocol to a single-command interface and introduced a generic driver design using a finite state machine, improving maintainability and multicore support. Lesley also developed a user-level blocking I2C library to simplify integration and testing. Addressing compatibility, she renamed core I2C functions to prevent namespace collisions with LionsOS, ensuring stable builds. Her work demonstrated depth in C and Zig, leveraging skills in embedded systems, concurrency, and device driver development to enhance system architecture and code quality.
