Finally moved away from Wordpress as a back-end, which I pushed to the limit.
Learned Laravel and greatly improved my skills in vanilla PHP.
Moved from jQuery to Vue.js - it's now my default front-end framework.
Started using CLI and Git regularly.
Learned PWA, service workers, serverless, Web3, some Solidity, more MySQL, server admin, scaling.
Throughout 2018 I was coding all the time on my own, executing my personal projects. It was a great learning experience, and now I finally became a good and productive coder.
This is an achievement, because my first speciality is graphic design and I specialized in it for many years. Now I'm also a competent coder. When I combine design with code, possibilities are endless.
