I would love to work together!
Send me an email to get in touch.


I’m a self-taught developer that works with Ruby on Rails since 2009, when I picked up the ‘Agile Web Development with Rails’ book for Rails 2.1 and haven’t looked back since. I love the beauty of the Ruby language and the powertools Rails give me.

In recent years I’ve become familiar with both React and Vue and started to love TypeScript.

You can hire me to speed up your team. I have lots of experience across the full stack: from Rails on the backend to Vue and React on the frontend.

I write clean, tested code. I have a strong Product focused background, having worked in Product related roles for years as well. I focus on delivering impact and a great user experience.

🚀 Products
