Magento2, HTML, CSS(LESS for Magento2), PHP

JavaScript, (jQuery and Require for Magento2) AngularJS and maybe.. Vue.js? Or React? But I also need to fix my Wordpress site.. so much to do! All fun things.

In my free time I play on CodePen, am working on the FreeCodeCamp certifications and CodeCacemy WebDevelopment Path. Also got me a ClockworkPi that I am hacking, but I got stuck. recenty I discovered podcasts, love this.
At work, I am working fulltime on Magento2, getting into CSS Grid for my current project, and love it! So at work and at home, I am still learning a lot.

QUESTION! From time to time I do wonder if my code is good, I mean, it works on the front-end, but I just wonder if it could be better, more DRY, more efficient etc. Any help or tips are welcome!
