Go to university & get a degree. A degree opens a lot of doors in the future, even if you think it shouldn't matter. That's both simple things like "Getting your CV past a clueless first-screen HR person", and complex things like "Applying for a visa to live/work abroad".
Also, if you're working as a developer already then the first year of university is likely to be straightforward for you. Depending on the hours, you could probably keep the part-time job and study (but out of the two, you should prioritise the study).
Finally, I'd recommend you use your free time in university well. Volunteer for charitable organisations; help out with your student union; take up a sport; keep learning things not on the curriculum. All of these are fulfilling in and of themselves, but will also benefit your future too.
