I'm from another background than most of you. I had an (online) marketing agency, did some webdesign and most of my experience lays in sales.
Next to my job I'm following courses on data science (big data), project management and organizational analysis. However, development and programming keeps interesting me. (As a kid I liked building websites, still do!)
I've finished the CodeAcademy Ruby tutorials, watched some videos and read a lot. Now I feel I got the basics and want your input for intermediate level courses/tutorials.
Got any tips to take my knowledge to the next level?
If you're a tech person that could use some sales/marketing advice, feel free to let me know!
