My name is David W Parker and I’m creating and publishing videos on ProgrammingTIL to help teach anyone and everyone who wants to code. I’m a huge fan of Ruby on Rails, Svelte, TailwindCSS, and WebGL. I’ve used React a lot in the past, as well as some Vue and AngularJS. I’ve done some professional Python and Django. I like to create real applications and my tutorials will walk you through how to build something real from beginning-to-end.
