I'm launching my first vibe coded SaaS product.

I vibe coded my first SaaS product. Here's the journey to the build.

I'm launching my first vibe-coded SaaS product, and I want to share my lessons with you 🎉

Let’s face it: most PM interview prep is broken.

Candidates will spend 40+ hours reading Cracking the PM Interview, memorizing frameworks, practicing with friends/family, but when the Zoom camera turns on, we freeze.

We know the theory, but we haven’t built the muscle memory.

That’s why I built PM Interview Coach.

I wanted to create a “Virtual Meeting” environment where you can practice your verbal delivery with an AI-interviewer that tailors the interview to you, your target job, and the answers you’re providing turn-by-turn.

When you complete the interview, it doesn’t just give you a “pass/fail,” but a tailored feedback rubric with a question-by-question replay.

And unlike your friends or partner, it’ll practice with you at any hour of the day 😂

Check out the demo here:

Founding Subscriber Special

To celebrate the launch, I’m offering a Founding Subscriber price of $9.99/month. This gives you unlimited sessions, company-specific interviews, and downloadable performance reports.

What I learned from building this

I’ll be honest, this build pushed me. When you start vibe coding an app, it feels like magic. But the “boring” backend is where the real battle happened.

That moment when your CAPTCHA finally works!

To make this a launch-ready product, I had to wrestle with:

• API integration: Integrating with an LLM (Gemini) to power the interview coach.

• Login & captcha: Tracking user payments, token limits, and implementing bot protection using Captcha.

• The Payment Wall: Integrating Stripe to handle subscriptions seamlessly.

• Token Rate Limiting: Protecting the app from “bot” usage and managing high API costs with strict monthly token cap.

• Deployments: learning how to deploy an app and set up custom domains.

The struggle was real, but it was all so worth it in the end.

Coming Soon: My Vibe Coding into Production Guide

Building this tool taught me a lot about how to create a launch-ready app.

I’m currently polishing a deep-dive guide on how I went from idea to a paid product.

If you want to learn how to build your own project without getting stuck in the backend “muck”, you won’t want to miss this.
