I’ve always been a builder. Whether it was my own startup or working within a 140-year-old company, the goal was always the same: make tech useful for normal humans.

Lately, the buzz around “vibe coding” has doubled since I started doing it summer 2025. The main reason is because AI coding agents are significantly better and can actually give a non-technical builder superpowers. I decided to put this to the test in my new series, where I give myself just 10 minutes to live-vibe-code an app. No dry runs, no scripts, no edits.

The "10-Minute" Plan

I chose a "softball" project for the first episode: a simple countdown timer.

My requirements were simple:

  • A fun and playful visual style.

  • The ability to count down into negative numbers.

  • Numbers that turn red when time is up.

  • A chime notification when hitting zero.

I used Claude Code as my primary tool, following my own first rule of vibe coding:

Pro Tip: You don’t need a perfect prompt. You just need to start a conversation.

The Reality Check

I started the clock at [02:53], and Claude quickly guided me through the design process, asking smart questions about architecture and visual style that I hadn't even considered. Admittedly, this is my first time using Claude Code to build from scratch since a few months ago, and this “brainstorming” skill blew me away. It recommended a single HTML file approach—simple, clean, and portable [08:15].

By the 8-minute mark, Claude didn’t even start coding yet; it was still writing documentation [10:38]. Writing the design doc and implementing the actual code took longer than my 10-minute window allowed.

Spoiler alert: The "10-minute" app actually took closer to 30 minutes to complete [13:38]. But the build process is extremely comprehensive.

The Lesson: Compound Learning, Not Just Consumption

Most people overestimate what they can do in a week but underestimate what daily compounding can do in a year.

What I learned from this experiment:

  • Vibe coding isn't "magic." You still need to make product decisions. AI is a guide, but you are the strategist.

  • Time management is different with AI. The brainstorming is fast, but the "implementation" phase still requires patience, tweaking, bug fixing, and sometimes endless iterations.

  • Expectation vs. Reality: 10 minutes is enough to prototype, but 30 minutes is what it takes to get a (very simple) functional, bug-free product [13:38].

Does it work?

In the end, the app was exactly what I asked for. It has a playful theme, custom presets, and yes—it blinks red and chimes when it hits zero [14:31].
