How do you start building a social app from scratch without getting overwhelmed?

Start with the thinnest usable version instead of trying to build the entire social network. A sensible first flow might be signing up, creating one post, and viewing posts. Sketch your core data models—probably users, posts, and follows—and the few screens needed for that flow before you code.

You can add authentication, profiles, password recovery, and other features afterward. Use tools you already understand, and feel free to use AI for scaffolding repetitive forms or brainstorming edge cases, but keep the core product logic simple. Most edge cases become clearer once real people use the basic version.

It’s normal for personal projects to feel harder than internship work because you’re responsible for the product decisions, architecture, and prioritization as well as the code. Don’t aim for a perfect first version. Build something rough, test it, and improve it based on what actually breaks or confuses users.

Writing tests as you go can help catch important problems, but you don’t need to solve every hypothetical case before anyone has used the app. Give yourself permission to change the design as you learn.

A practical order is to build a basic landing page, authentication, and account recovery first. Then create a simple profile and add the main interaction through that profile. Keep each step small enough that you can run and test it before moving on.

The first version is allowed to be ugly. The goal is to prove the central experience works, not to produce production-ready infrastructure on day one.
