Worked on the spring-kafka repository to standardize Dead Letter Topic suffix references, updating them from '.DLT' to '-dlt' throughout Javadoc, reference documentation, and code samples. This change addressed outdated naming conventions, reducing user confusion and minimizing support overhead by improving consistency across documentation and code. The approach involved careful review and modification of both Java source files and AsciiDoc documentation, ensuring that all references aligned with the new convention. Demonstrated skills in Java, documentation practices, and repository-wide naming governance, contributing to clearer onboarding and fewer misconfigurations for downstream users. The work focused on maintainability and user clarity.
