Over a three-month period, contributed to the perses/perses and open-telemetry/opentelemetry-collector-contrib repositories by delivering targeted features and reliability improvements. Developed a dashboard usage metrics tracking system in perses/perses, implementing a frontend UsageMetricsProvider in React and TypeScript to monitor user interactions and securely transmit data via a Go-based API. Enhanced the Query Editor with a manual Run Query button, improving user control and workload management using Material UI. Addressed a critical bug in open-telemetry/opentelemetry-collector-contrib by refining test context handling in Go, which reduced segfault risk and improved CI stability through more reliable health check testing.
