I'd like to move deeper into the backend. 2017 has been mishmash for me; I learned a bit of everything -- Elixir, Erlang, Golang, Python, Java -- and got nowhere. But I managed to learn Vue.js and put it into production for a client, which I'm proud of. In 2018, I plan to focus more on "real" backend development -- design patterns, algorithms and data structures, database optimizations, scalability . . . all those things.
