I’ve been coding for a long time (20 years give or take) but it has been largely hobby or part-time coding, not my full-time job. I know a lot but there is a lot I don’t know. I’m entirely self-taught so it is easy for gaps to appear. This page is my attempt to compile the information I need to improve my development skills and to create a reference I can look back at in the future. If you find it helpful, awesome!
