Lara developed and maintained core hardware validation and firmware infrastructure for the bittide-hardware repository over 11 months, focusing on robust memory mapping, hardware abstraction, and test automation. She introduced a Hardware Abstraction Layer and streamlined code generation, leveraging Haskell, Rust, and C to improve type safety, data handling, and cross-language integration. Her work included refactoring memory map validation using functional programming techniques, enhancing error reporting and maintainability. By implementing features such as zero-width register support and HITL test monitoring, Lara enabled more reliable hardware-software integration and accelerated debugging cycles, demonstrating depth in embedded systems, build automation, and hardware description languages.
