Since other comments already point to getting a job, I'd mention other options. One is going to university and being exposed to more technologies and most importantly, meeting other people and working with them. Other similar options are going through the syllabus yourself and partnering with other people in hackathons or similar group events. I would like to also offer a different perspective on the idea of "big" web apps or more "professional" setups. If what you want is to be able to do more complex projects for your customers or for yourself, just do that. Solve the problems you need to accomplish your goals. Maybe your development cadence could improve from getting better at testing. Maybe you're not happy not knowing how to maintain or deploy your code. Focus on your path and your problems and forget about what you "should" be doing. That's how most people become proficient engineers. Meanwhile keep up with industry news and read a few books per year, and know that the best way to really kick this into overdrive is working alongside more experienced people in a team.
