I put forth a strategy for managing static assets for multiregion setup, it involved categorizing the static assets based on the end users and who uploads it. I implemented a solution for each category, helped team to migrate from old s3 bucket and CDN to new setup. And the hard part here was understanding the current requirements of various teams and also design a solution which is flexible for future expansions as well. For which I had to collaborate with various teams in the organization, convince them and help to migrate to the new setup without any downtime
