Build
anything.

After years of failed businesses, I’m still chasing $100K a month. Now I’m building apps, and you can use most of them.

Things I’m building, learning, and finding worth sharing.

Cool stuff I’ve built.

Apps, widgets and tools I’m building. Everything I finish is free to use, with guides to build your own.

See all projects

Ten chapters of failures, small wins, and everything that got me here.

  1. 01

    $100K/mo

    The goal.

    That’s the number I’m chasing. Enough to buy back my time, give the people I love an incredible life, and eventually buy the Ferrari I wanted as a kid.

  2. 02

    I was 17 when this whole thing started.

    At 17, I moved to the US and discovered the whole make-money-online world. I started Instagram pages for everything from fashion to fitness. None lasted long enough to become anything.

  3. 03

    $150 → $300

    My first money online.

    During COVID I built a home-gym dropshipping store. It actually worked. Then I got scared, hit problems I did not know how to solve, and shut it down.

  4. 04

    21 for 21

    Every US college said no.

    I wanted to go back to America. Instead, I ended up in Barcelona, got a scholarship, and immediately tried another business.

    Zodiac mugs. Sales: $0.

  5. 05

    400+

    Videos almost nobody watched.

    I made more than 400 YouTube Shorts over two years and reached about 750 subscribers.

    Eventually I realized something painful: nobody really wants business advice from someone who has not built a business yet.

  6. 06

    $3,000 → $400

    The expensive lesson.

    I turned an idea from my university thesis into a real store and spent around $3,000 trying to make it work.

    Revenue: about $400.

    More money did not make up for the skills I was missing.

  7. 07

    0 → 1

    The thing I was never good at.

    Ideas were easy. Improving things was easy. Criticizing things was definitely easy.

    But taking something from nothing and actually building it? That was always the weakness.

  8. 08

    6 years

    One spreadsheet changed everything.

    I had tracked my workouts in spreadsheets for six years. Then I used AI to turn the system in my head into my first real app.

    For the first time, I could actually build the things I imagined.

  9. 09

    5+

    Then I kept building.

    Workout apps. Finance tools. Widgets. Calculators. Random experiments.

    Some useful. Some probably pointless.

    But each one makes me a little better at turning ideas into real products.

  10. 10

    Now

    Still figuring it out.

    Years of failed businesses. Hundreds of videos. Thousands of dollars burned.

    I still haven’t reached $100K a month. Right now I’m building apps to get there, and tomorrow I might pursue a completely different idea, but the goal stays the same.

Stuff I’d send a friend.

Every week, I share what I’m building, what I’m learning, and the few things I found worth passing on.

Business, products, AI, useful tools, mistakes and whatever else is moving me forward.

  1. Friend: bro new ChatGPT image model just dropped

  2. Me: bro I’m literally at work

  3. Friend: it can do transparent PNGs now

  4. Me: onmw
