I'm working on a social media app that has received some early validation. I'm a computer science major with several software internships, so I'm comfortable coding and working with technology. The difficult part is starting from a blank project and deciding what to build first.
As I map out the product, I keep discovering a huge number of edge cases I hadn't considered, which makes the project feel overwhelming. I'd appreciate practical advice from experienced developers on how to break an app into manageable pieces, decide which features matter initially, and build efficiently without getting stuck trying to make everything perfect.

Start with the smallest usable flow instead of planning the entire platform. For a social app, that might be signing up, creating a profile, making one post, and viewing posts. Sketch the main screens and basic data models—such as user, post, and follow—before coding, then ignore most edge cases until you know they affect real users. You can use familiar tools or AI assistance to scaffold repetitive pieces like authentication and basic CRUD, but keep the product logic simple and use a stack you already understand.
Build the roughest version that demonstrates the main idea. A reasonable order is a landing page, authentication, profiles, and then the core interactions between users. Don’t spend weeks making every screen polished before anyone tries it—the important thing is getting a working loop in front of people quickly.
The edge cases will always seem endless when you’re working alone. You usually learn which ones actually matter only after people use the product, so it’s fine to postpone the less important cases.
The difference between internship work and a personal project is that internships usually provide the architecture, requirements, and established conventions. When you build alone, you have to make all those decisions yourself. Treat this as part of the learning process, give yourself permission to change direction, and don’t expect the first version to be perfect. Keep notes on problems as they appear, add tests for important behavior, and improve the app incrementally instead of trying to solve everything up front.

That makes sense. Focusing on one complete flow instead of the whole social network feels much more manageable.
