Bablu Kumar developed an API performance benchmarking framework for the boxyhq/jackson repository, focusing on core integrations such as SSO, Directory Sync, and SCIM endpoints. He implemented load testing scripts using JavaScript and k6, establishing a repeatable process for measuring and validating the performance of critical API endpoints. Bablu documented the setup and results in a comprehensive README, providing clear instructions and baseline metrics to support data-driven optimization and capacity planning. His work enabled the team to monitor and improve integration performance, laying the groundwork for better adherence to service level objectives and more informed production workload management.
