During six months on the Netflix/metacat repository, Jursetta modernized core platform components and enhanced observability by upgrading to JDK 17 and Spring Boot 3, migrating persistence APIs, and removing legacy dependencies. She implemented granular performance and error monitoring using Java and Spring Framework, introducing percentile timers and error tagging to improve latency tracking and diagnostics. Jursetta addressed API stability and caching reliability, refining connector services with explicit cache configuration and restoring stable API behavior. She also expanded database metadata support in the Polaris Connector, updating schema and CRUD logic with Groovy and SQL, and validated changes through comprehensive automated testing.

Oct 1, 2025Summary for 2025-10: Key feature delivered: Polaris Connector now supports database parameter metadata (DBS_PARAMS), aligning with the HMS connector. This included updates to create, update, and retrieve logic, schema evolution, and new tests validating metadata handling. Major bugs fixed: none reported this month. Overall impact: delivers parity with HMS, reduces integration risk, and enables metadata-driven configurations across deployments. Technologies/skills demonstrated: connector development, schema evolution, test automation, and end-to-end capability validation.

Jul 1, 2025Summary for 2025-07: Implemented focused instrumentation enhancement on Netflix/metacat to improve failure visibility and diagnostics. Key feature delivered: granular request error tracking by adding a request_error tag to percentile timers when exceptions occur (UnsupportedOperationException, IllegalArgumentException, and general Exceptions) within the RequestWrapper. This enables more granular insights into request failures, improving dashboards, alerting, and MTTR. No major bugs fixed for this repository this month. Overall impact includes faster triage, better reliability signals, and data-driven improvements to user-facing and internal services. Technologies exercised include metrics instrumentation, exception handling, and code instrumentation in RequestWrapper, with a clean, single-commit delivery and clear traceability.
