Why wouldn't there be a place for you? Web technologies are only going to increase in importance. If you're worried about competition, you'll need to get over that. Fear of competition comes from a scarcity mindset. Instead of focusing on what other people are doing (the competition), choose to focus on increasing your own skills and value. If you do that, you'll naturally surpass those people who choose to become complacent and put in the bare minimum. You have a marketing background, so that helps a great deal. There's no shortage of talented developers, but there are a shortage of talented developers who know how to market themselves and present their ideas and value to clients. If you're skilled at what you do AND you know how to market and sell that value to clients, the sky's the limit for you.
It's not so much competition, but I have heard a lot recently about there being a web dev bubble of sorts. Especially with me being 1 year out from being a solid junior dev I just wanted to get the take of those in the field already.
My sense is that there's a salary bubble, but not a job bubble. I think it would make sense to expect average webdev salaries in a few years to be lower than today's. Still seems to me like it's a good time to start learning, though!
