What's next for someone interested in programming and Linux?

So today I passed the CCNA exam after 1 month of studying... I used exclusively Jeremy's IT Lab free videos (thanks man, you are the best!), but I had some previous knowledge of computer networking (mostly theory, from a university course). Did JITL labs and anki flashcards daily, but because of lack of time I didn't do his mega lab, nor the boson exsim (which I had purchased but never opened it and returned it back today for a refund).

Now I wonder what to do next. In addition to CCNA, I have a solid knowledge of Python programming and Linux. Any suggestions? What roles combine these three? Should I apply for them or pursue other certs? Thanks in advance!
