Worked on the doocs/md repository to deliver a feature focused on enhancing file upload performance and scalability. Developed and integrated a useCDN option, allowing users to toggle between standard GitHub hosting and CDN-accelerated uploads. This approach leveraged JavaScript and Vue.js to improve asset delivery speed and reduce latency for end users. The solution provided a more flexible hosting strategy, supporting both traditional and CDN-based workflows. Throughout the process, collaborated effectively on code reviews and managed pull requests to ensure smooth integration. No major bugs were addressed during this period, with efforts concentrated on front end development and performance optimization.
