Worked on the valkey-io/valkey-iohub.io.git repository to enhance the reliability of CPU affinity management within the blog-post workflow. Addressed a misconfiguration in IRQ range allocation by updating a Bash script, ensuring that IRQs 48-51 are mapped to affinity 1000 and IRQs 52-55 to affinity 2000. This targeted bug fix improved balanced interrupt handling and reduced the risk of performance anomalies during testing. Leveraged skills in performance tuning, system administration, and technical writing to document and implement the solution, with changes tracked for traceability. The work focused on correctness and reproducibility in automated test pipelines using Bash and Markdown.
