Github User Search App With Tailwind CSS

This was fairly straightforward to me. On the UI side of the house, I'm curious how everyone handled the avatar between desktop (two-column setup) to mobile (one-column setup). I ended up using Flexbox but had to create an additional image element and hid it on mobile. What's the best solution?

Querying the API was straightforward. I was tinkering with trying to pull in all of the UserNames in GitHub and display the top 8 or so as the user types the name (similar to Google). The end user may know the name of the person but may not know their username, so I thought this would be a useful feature. In the end, there are way too many usernames to try to download and the API would only let me do it through paginated results. Does anyone have an idea how to tackle this if you needed to?
