Worked on backend stability and feature upgrades across apache/spark and linkedin/openhouse repositories, focusing on reliability and compatibility. Delivered a fix for Spark’s Shuffle Service metrics deserialization, improving the accuracy of metrics logging and retrieval in Scala-based Spark History Server workflows. Enhanced observability for shuffle metrics, reducing discrepancies and supporting more effective monitoring. Upgraded the Iceberg library in OpenHouse to version 1.5.2.4 using Gradle, introducing new API features while preserving backward compatibility for downstream applications. Employed Groovy, Scala, and API integration skills, validating changes manually to ensure seamless upgrades and stable behavior without introducing breaking changes or regressions.
December 2025 update for linkedin/openhouse: Delivered an Iceberg library upgrade to 1.5.2.4 with compatibility enhancements and preserved behavior. Implemented client-facing API changes via PR 2398c422 (PR #416), including new features and a default compatibility flag. No automated tests were added; manual validation completed. This work reduces upgrade risk for downstream apps and prepares the project to leverage Iceberg’s latest capabilities.
