PROFILE

Marko Bachvarovski

Developed a configurable Supervisor ID feature for the opentelemetry-collector-contrib repository, enabling collectors to accept a user-provided instance ID during pre-registration. The implementation included UUID validation logic in Go, ensuring that only valid IDs are persisted, while automatically generating a random ID if none is provided or if the input is invalid. Enhanced the persistence layer to guarantee immutability of the Supervisor ID after the first launch, and expanded test coverage to address edge cases involving missing or malformed IDs. Collaborated with contributors to update documentation and align the feature with project requirements, demonstrating strong backend development and Go expertise.

March 2026: Delivered a Configurable Supervisor ID for collectors pre-registration in the opentelemetry-collector-contrib repository, with UUID validation and enhanced persistence handling. Implemented logic to accept a provided Supervisor/instance ID, validate it as a UUID, and fall back to a randomly generated ID when absent or invalid. Expanded tests for the persistence layer to cover scenarios where instance_id is provided, invalid, or missing, ensuring immutability after first launch. Updated documentation and coordinated with contributors (co-authored-by Alex Boten) to align with the tracking issue #45596.
