I am a developer who first started coding on gmod making addons. I then found out that once you know one langauge, it's easier to exapand to others, so that's exactly what I did.
Lets be honest, HTML is nothing without CSS. Some people don't even consider it a language because it's so easy to learn (hint: you should learn it becuase it's easy)
Lua was the first language I started on. I used it to make crappy gmod addons. I have moved on from Lua and don't really use it anymore, but it was a great start.
PHP is my favorite language. This is becuase I am the most skilled in the backend department and it's pretty cool in general (although some might disagree).
While my knowledge in CSS is acceptable, I lack skills in the creativity department.
I'm very good with the linux operating system, specifcally Ubuntu Server. I'm currently hosting this website on my own servers!
