Worked on the firedancer-io/firedancer repository to deliver a targeted transaction context refactor and rent tracking enhancement focused on improving correctness and thread safety in transaction processing. The approach involved making the slot context a const pointer to reduce data races in multi-threaded environments and introducing a collected_rent field to accurately track rent gathered during transactions. Rent collection logic was updated to sum into this new field, enabling more reliable financial metrics and auditability. The work leveraged C and system programming skills, with attention to concurrency control and memory management, while preserving existing APIs and performance characteristics for future scalability.
