The business & tech world moves at such a fast pace that we just have to learn new skills to get the job done.
I'm a data analyst 1 day, a software engineer the next, and a quality assurance inspector another. I've picked up machine learning a bit to try to help with our internal algorithms, and occasionally I'll even do some html/css coding for automated emails (essentially web design)
Languages I've learned.
Frameworks/Libraries I've used.
Per month I spend studying.
