Worked on the grafana/pyroscope repository to implement tenant-level configurability for self-profiling in single-binary deployments. Developed a feature using Go that allows specifying a custom tenant ID via a new configuration flag, enabling per-tenant data streams while maintaining privacy when the flag is not set. This approach strengthens multi-tenant data isolation and supports compliance requirements, laying the foundation for more granular analytics and governance. Updated documentation and reference configurations to reflect these changes, ensuring consistency at deployment. Collaborated with other developers through co-authored commits and cross-team reviews, focusing on backend development and ongoing improvements to configurability and maintainability.
