Startup-experienced Backend Developer Seeking New Opportunities

Tried founding my own startup but decided against raising capital since initial traction was hard. The project is now open-source and I'd like to continue maintaining it since it does have a few users and I still believe in the value it provides. But I also want to work in a larger team again on a more meaningful endeavor. I have 4+ years of startup experience of various sizes and have done a lot of different jobs in those. Definitely a backend focus, but wouldn't mind learning anything new, I tend to pick things up quickly. I have some leadership and product management experience and wouldn't mind doing that again as long as I can keep somewhat hands-on.
