Worked on enhancing the reliability and maintainability of Office365 data ingestion within the opensearch-project/data-prepper repository. Focused on backend development using Java and the Spring Framework, refactoring the RetryHandler into the source crawler package to improve modularity and consolidating error-handling pathways for more resilient API integration. Strengthened the retry logic in Office365RestClient to better handle transient failures, reducing data loss and improving data freshness for downstream analytics. Additionally, implemented a customized retry handler to stabilize and accelerate test runs during token renewal scenarios, reducing test flakiness and supporting faster, more reliable integration testing through improved unit testing practices.

Dec 1, 2025December 2025 — Focused on reliability and maintainability of Office365 data ingestion. Implemented the Office365 API Retry Reliability Enhancement by refactoring the RetryHandler into the source crawler package to improve modularity and maintainability, and by strengthening the retry logic in Office365RestClient to better tolerate transient API failures. These changes reduce ingestion interruptions and improve overall data freshness for Office365 data streams, supporting more robust downstream analytics and reporting.
