PROFILE

Siqi Ding

Worked on the opensearch-project/data-prepper repository, delivering features and enhancements focused on server architecture, authentication, observability, and data ingestion. Built a unified server and authentication framework using Java and gRPC, centralizing plugin integration and improving security. Enhanced observability by implementing configurable metric filtering through YAML-driven settings. Improved the S3 Source Connector with incremental partitioning and global state renewal, optimizing large-scale data ingestion using the AWS SDK. Strengthened configuration validation by introducing a custom Jackson deserializer, reducing runtime errors. Maintained code health through dependency upgrades and robust exception handling, demonstrating a disciplined approach to software maintenance, testing, and distributed systems development.
