Congrats on the progress you have made, and also for realising what your preferences are. First: Finish your degree - a valuable and important signal to employers is that you finish things, not start and stop whenever you have a change in emotion. It's ok to feel discouraged sometimes, but it's never ok to quit what you're supposed to finish. Second: Your data science experience is very valuable already, and so once you start learning SWE, you have a good mix of skills that many of your peers with only data science or SWE won't have. Third: I still like Ruby on Rails for web app development, and there is still a ton of opportunities out there for employment on it. So think about learning that. To incorporate data science into web apps for production, there are a lot of options, and Rails will keep you productive with moving forward and learning more in that field. Good luck, and congrats on your upcoming graduation!
