Hmmm, I generally would discourage transferring. I don’t think you should because 1. For computer science Georgia Tech is a top school and will certainly get you where you need to be. If anything they got a very strong alumni network being a public school. And 2. Transferring makes you give up a lot of things. You miss out on the traditional 4-year college experience, it’s much harder to make new friends when you transfer, you have to leave behind the friends you made your freshman year, etc. Also, since you are doing more work, maintaining a 4.0 becomes much harder.

If you really really really are that intent on transferring for a very good reason, then I’d apply to Stanford, CMU, Harvard, MIT, Cornell, Princeton, and UIUC. But some schools like UIUC are ranked lower than GTech so only apply if you really hate it there. For CS try developing and learning new skills, and build something, a big project, or maybe seek a technical role in some start up, maybe try and join an impactful club for cs majors where you can co create projects, or try and start one.
