I'm an experienced developer, but an inexperienced indie hacker.

Well you have come to the right place 🤗 Start reading through some posts and give your feedback. I'm sure plenty of us will benefit to hear your side of development which some lack in.

I'd really recommend reading some of the interviews, listening to some of the podcasts and just hanging out here reading what people ask and answer with. Taking in bits of information over time will help you get a feel for things you could potentially start tackling/doing.

I mostly tend to follow posts related to marketing, SEO and UI/UX to learn this stuff. I ask questions about things that I have hard time understanding. There is also a "tech-questions" tag here you can help others who are need help on tech side.
