PROFILE
Nissim Shiman
Worked on Apache NiFi, delivering targeted improvements to backend reliability, auditing, and operational clarity. Enhanced the ConsumeJMS processor to ensure consumer connections are properly closed when a node loses primary status, reducing resource leaks and supporting safe cluster failover. Added integration tests to validate this behavior. Developed Process Group lifecycle auditing in Flow Configuration History, enabling detailed logging of start and stop actions for both internal and remote process groups to improve traceability and compliance. Addressed log noise in WebApplicationExceptionMapper by suppressing stack traces for OK HTTP responses. Utilized Java, distributed systems concepts, and unit testing throughout these contributions.
