PROFILE
Piotr Bartkiewicz
Worked on the trinodb/trino repository over three months, focusing on backend development and cloud integration. Built centralized metrics instrumentation for data exchange operations, extending observability to the FileSystemExchange component and exposing metrics via SPI for dashboards and alerting. Enhanced the data-exchange path by classifying storage types, implementing conditional encryption for external storage, and maintaining backward compatibility in configuration management. Improved test infrastructure reliability through targeted refactoring and stabilization. Delivered Azure Storage Connection Pool Tuning, introducing new configuration properties to optimize concurrency and reliability. Demonstrated expertise in Java, cloud computing, and performance monitoring while addressing scalability, security, and maintainability challenges.
