Why trust me

I've built and sold eight Chrome extensions.

From a year's salary at 19 to a 4-hour AI build that sold in five days. Here is the whole story — including the one I had to shut down.

The story, in seven steps

  1. Age 19

    My first extension paid a year's salary

    I left home at 16 to study programming. At 19 I sold my first product — a Chrome extension — for about what an average Ukrainian earned in a year.

    A fan of hundred-dollar bills in front of a laptop spreadsheet.

    ≈ a year of salary

  2. The pattern

    I didn't invent it. I built it better.

    A client paid me to build an extension that controls the volume of one tab. I noticed people were searching for exactly that, and nobody was building it well. So I built my own.

    30,000 weekly users → sold

  3. Again

    Then I rebuilt it from scratch

    Same idea, better execution — and this time I knew something about getting found in the store.

    100,000 users → sold again

  4. 3 days

    A "stupid" Color Picker

    Three days of work. Then a year of waiting while the store kept sending people to it.

    100,000 weekly users → sold for $20,000

  5. The miss

    The one I shut down myself

    An extension that automated Instagram peaked at $800 a month. Then Instagram started blocking my clients' accounts, so I killed it. Since then I only build with a platform's rules, never against them.

    $800 a month → $0, by choice

  6. Side project

    All of it on evenings and weekends

    None of this was my main job. I freelanced, worked for companies and built fitness apps — one reached half a million downloads. I sold that whole portfolio this year.

    Working late on laptops at a kitchen table.

    8 extensions sold · $100,000+ · $0 on ads

  7. Now

    4 hours with AI. First sale on day five.

    Mobile got crowded: the supply grew, the audience didn't. The Chrome Web Store still works the way mobile did five years ago. So I tested it — I built an extension with AI in four hours. Five days later, someone I'd never met bought it.

    Standing on a ridge above a sea of clouds.

    4 hours of work → first sale on day 5

What it taught me

Three things I'd tell myself at 19

  • 01

    Pick before you build

    The extensions that paid me were chosen, not invented. How I choose is the first playbook.

  • 02

    The store is the marketing

    I never bought an ad. The Chrome Web Store sent the users — how to make it do that is the second playbook.

  • 03

    Code is no longer the moat

    AI writes it now. What's left is knowing what to build, how to rank it and how it pays.

    Extension AI Kit

The plans are these three lessons written down, with AI skills that do the building — so you skip the 8 years of trial and error I paid for.

“Honestly — I'd love to be starting today.”

You can. Get the whole system for $249, or work with me until your first sale.

These are my results, not a promise of yours — earnings disclaimer.
