Worked on the sgl-project/mini-sglang repository with a focus on backend stability and correctness. Addressed a max sequence length overflow issue by introducing an align_down function and recalibrating the max_seq_len calculation to account for both configuration and page count, ensuring robust handling of long sequences. The solution was implemented in Python and leveraged skills in algorithm design and data structures to deliver a maintainable fix. No new features were shipped during this period, as the primary emphasis was on improving reliability and preventing edge-case overflows, resulting in a more stable and predictable backend for sequence processing tasks.
