Kelliott developed a Reactive Streams Emission Lint Detector for the slackhq/slack-lints repository, targeting rxObservable and rxFlowable usage in Kotlin and Java codebases. The detector enforces that send or trySend calls are present within reactive stream lambdas, addressing the risk of silent non-emissions and improving code reliability. Kelliott’s approach included comprehensive static analysis, integration with Slack’s lint issue registry, and thorough test coverage to validate detector behavior and edge cases. By leveraging skills in RxJava, linting, and coroutines, Kelliott enhanced the maintainability of reactive code paths, providing a robust solution for traceability and remediation of emission issues.
