Worked on the tangly1024/NotionNext repository to refactor AI configuration management, focusing on improving code reliability and maintainability. Centralized AI-related settings into a dedicated JavaScript configuration file, replacing scattered config files and establishing a single source of truth for AI integration. Updated validation scripts and fixed references to Prettier configuration files, ensuring consistent formatting and smoother CI validation. Removed obsolete and misspelled configuration files to eliminate dead code paths and reduce potential misconfigurations. This work enhanced onboarding and maintainability by streamlining configuration management, leveraging skills in JavaScript and configuration management to deliver a cleaner, more robust project structure.
