Vibe-Code a Working Web App
Maps to: Software Engineer · Product Manager · Founder · Designer
You're going to build a real web app for one thing you wish existed, and put it live on the internet where actual people can use it. The skill is scope: deciding the ONE job it does well, cutting everything else, then shipping it and fixing what breaks when a real person tries it. That's the core of software engineering, turning an idea into a working thing and deciding what not to build, and doing one tells you fast whether shipping a live product is your kind of work.
How this shows up on a resume or college app
I built and deployed a working web app for [user persona], taking it from a vague idea to a live URL real people use, then cutting it to the one job it does well after watching them. I learned that the hard part of shipping software is the judgment: deciding what to build and what to leave out.
When you finish, BuildMe drafts your Common App activity description from what you actually built.
The plan
- 1
Step 1
Pick the one thing it does, and who it's for
Don't open a tool yet. Pick one thing you personally wish existed, name the one person it's for (it can be you), and write, in a single sentence, what it does and the pain it kills. Sketch the screens on paper. This one-paragraph spec is the thing that keeps your app from sprawling into a mess.

Steps 2–4
Build it and ship to a live URL
Now build. Describe your app to an AI builder, iterate, and deploy to a real URL. Use small, specific prompts: 'make the button blue and move it under the form' beats 'redesign this.' Get it live even if it's rough.

Step 5
Use it for real, then cut it to the one job
Use your own app for an actual task. You'll immediately feel what's broken, confusing, or pointless. Now make the real engineering decision: what's the ONE job this must do well, and what are you cutting to protect it? Then fix that one job.

Step 6
Share with 3 people + ship one round of fixes
Send your URL to 3 real people and watch (or ask) what trips them up. Pick the one fix that matters most and ship it. Then it's real: a thing you made, live, that people used.
