finnhub.io has a nice API for getting finance and stock information. They are the ones I used for this.
The next plan is to create a mini course for entry level engineers to learn some frontend development. I don't really plan on updating this site much though.
I was not really planning on this much. Did it this weekend as a project. However, I do plan on making youtube videos on how this was built to teach upcoming developers as part of this startup I'm working on called codefogo.com.
