I'm what you would call a 'front-end' engineer. Senior front-end developer is my current title, though I'm quite capable of full-stack development. I make $103,000 annually and do not have a college degree. There has never been a job that denied me due to lack of education because I've been able to prove myself and my abilities. Going to college is a great resume boost, but has had no bearing on my career thus far.
