PROFILE
Wink
Over four months, this developer enhanced the apache/flink-cdc repository by building features that improved data transformation, pipeline flexibility, and deployment modularity. They implemented schema-evolution aware projections and table sharding, refined time handling in pipelines, and fixed decimal precision issues using Java and SQL. Their work introduced batch execution mode for CDC YAML pipelines, enabling scalable batch processing alongside streaming. They also decoupled Kubernetes dependencies from flink-cdc-dist, promoting modular architecture and easier deployment. Through comprehensive integration and unit testing, as well as updates to documentation, the developer demonstrated depth in backend development, data engineering, and build optimization across complex distributed systems.
