PROFILE
Enrico Olivelli
Worked on the apache/celeborn repository to enhance cloud storage integration and reliability for distributed systems. Delivered features enabling secure AWS IAM role integration with Kubernetes EKS by extending Helm chart support, and improved S3 data handling by addressing edge-case bugs such as IndexOutOfBoundsException during reads. Optimized backend performance through targeted logging improvements and S3 multipart upload enhancements, leveraging Java, Scala, and YAML. Strengthened tiered storage workflows by fixing eviction logic during partition splits, validated with integration tests on real Kubernetes clusters. The work focused on production readiness, robust cloud infrastructure, and comprehensive test coverage to support scalable backend operations.
