Vibe Coding: Real Apps Without a CS Degree

ToolsSeptember 5, 20265 min read

What Vibe Coding Actually Means

I have a political science degree and a couple of business minors, not a computer science degree. I've still built more than 30 tools across my sites, a full dating platform from scratch, and a dozen interactive calculators for a multi-million-dollar Shopify store. None of that happened because I secretly learned to code the traditional way. It happened because I learned to build with AI doing the heavy lifting on syntax while I handled the parts that actually matter: what to build, how it should work, and whether it's any good.

People call this vibe coding now. The term is new. The approach isn't, not for me at least. I've been figuring out how to ship things I don't fully know how to build since I was 15, selling on eBay with zero business background.

Vibe coding isn't "no code." It's not dragging boxes around a visual builder and hoping for the best. It's writing real code, in a real codebase, with an AI model handling most of the syntax while you drive the decisions: what the feature does, how the data should flow, what happens when something breaks.

The skill that matters isn't memorizing React hooks or Python syntax. It's being specific about what you want, reading the output critically, and knowing enough to catch when something's wrong. That last part is the one people skip, and it's the one that separates a working app from a pile of code that looks fine until a real user touches it.

I still test everything by hand, and I still read error messages instead of just pasting them back into a prompt and hoping. The AI writes faster than I ever could, but I'm the one who has to know if what it wrote is right.

A four step loop: say what the feature does, the AI writes it, read it critically, test by hand with real data, then ship it to real users. When something breaks, read the console, trace the data and isolate the failure before asking the AI for a fix.

What I've Actually Built This Way

Here's what this approach has actually produced, not a hypothetical list. None of it required a computer science background. It required knowing the business problem well enough to describe it precisely, and being willing to sit with an AI model for as long as it took to get something that actually worked.

  • •DateIdeas.com (case study): a full React/Vite dating platform with 10+ interactive tools and generators. In active development.
  • •Digital Jesse tools: 30+ tools across SEO, social, business, and creative categories. Live at /tools.
  • •Quality Sewing calculators: 12+ interactive calculators for a 5,000+ product Shopify store. Live in production.
  • •Masterpiece Locator: an art discovery platform with 4,094+ paintings across 455+ museums. Live.

The Part Nobody Talks About: Debugging

This is where vibe coding either works or falls apart. When a feature breaks, you can't just ask again and hope for a better answer. You need to actually read what broke. I spend a good chunk of my build time doing exactly what a traditional developer does: checking the console, tracing the data, isolating the failure before I ask for a fix.

The AI is a fast typist with a huge memory. It is not a substitute for understanding your own product.

The Part That's Genuinely Different

What's changed for me isn't the thinking, it's the speed from idea to working prototype. A calculator that used to be a "someday" project on a list somewhere is now something I can build and ship the same afternoon I think of it. That compounding speed is why I've been able to build 30+ tools on top of a full-time e-commerce job, not because the tools themselves got easier to imagine.

Who This Actually Works For

Vibe coding works well for people who already understand a domain deeply and need to turn that understanding into software. It works less well for people hoping to skip understanding the domain entirely. If you don't know what "good" looks like for the thing you're building, an AI model can't tell you either. It'll happily generate a broken checkout flow with the same confidence as a working one.

I'd put it this way: vibe coding is a force multiplier on judgment you already have. It's not a replacement for judgment you don't.

Where I'd Start If I Were New to This

That's roughly the path that got me from spreadsheets and eBay listings to a live art discovery platform and a growing dating app. None of it started with a plan to "learn to code." It started with a problem I wanted solved and enough stubbornness to keep going until the tool actually worked.

If you want to see what this approach produces at scale, my full tool library has everything I've shipped this way, and my portfolio has the rest of the story on how I got here.

  • •Pick a real problem you already understand, not a tutorial project
  • •Build the smallest version that actually works, then use it yourself before adding anything else
  • •Learn to read error messages. You don't need to write them, but you need to understand them
  • •Test with real data, not the happy path an AI assumes by default
