Web developer looking to branch off due to an interest in psychology - what options would it open up?

So I'm 29, a web developer with 5 years of experience but getting somewhat disenamored with my work and instead spend most of my free time reading and listening to psychology (and philosophy as there's overlap) related material - books, audiobooks, lectures, discussions - basically hundreds of hours over the past 2 years or so and learning things about the psyche and the human nature excites me more than just about anything right now.

So I'm considering going back to university for a psychology degree (BSc, probably).

What would be some career paths that benefit from the degree along with my previous development experience? Ideally I'd like to combine them somehow.
