Contributed a core architectural refactor to the open-telemetry/opentelemetry-collector-contrib repository, focusing on improving code organization and maintainability within the Go backend. The work involved relocating mock structs for the receiver/aerospikereceiver component into an internal package, effectively eliminating import cycles and reducing module coupling. This approach leveraged Go’s internal package conventions and emphasized mock isolation, which simplifies testing and supports future modularization efforts. By consolidating these changes through a linked pull request, the developer enhanced traceability and code review efficiency. The update lays a foundation for easier refactoring and improved testability, demonstrating strong backend development and testing skills in Go.
