During the month, contributed to the sxjeru/lobe-chat repository by delivering the Bedrock AWS Regions Expansion and UI Enhancement feature. This work expanded the list of available AWS regions for the Bedrock provider and updated the region selector in the user interface, enabling broader deployment flexibility and improved geographic coverage for users. The approach focused on front-end development using React, JavaScript, and TypeScript, with attention to UI styling and alignment with design guidelines. No major bugs were addressed, as the effort centered on feature delivery and code quality, establishing a scalable foundation for future regional expansion and enhanced user experience.
