Worked on the thingsboard/langchain4j repository to improve the accuracy of documentation related to chat memory eviction policies. Focused on aligning the documentation with the actual implementation by updating references from MessageWindowChatMemory to TokenWindowChatMemory, which clarified guidance for developers integrating chat memory management features. Used Markdown for documentation and applied version control best practices to ensure changes were traceable and consistent across repositories. This documentation correction addressed a key bug, reducing onboarding confusion and potential support queries while preserving API stability. Demonstrated skills in documentation governance and domain knowledge of chat memory components, contributing to smoother user integration experiences.
