About me

I am a self-taught programmer from Tallinn, Estonia.

I have been a developer for over 5 years. Professionally, I mainly focus on creating websites with React and NodeJS, and native mobile apps with React Native. In my free time I also work with other programming tools.

My journey to programming may be an odd one. I started out my career by living all over Europe and getting two degrees in economics and finance, but I soon realized that the world of finance wasn't for me. Instead, I decided to dive deeply into programming and to switch fields to full-time software and web development.

I've always been interested by a wide array of fields — science, music, languages, to name a few — and with programming I found that I could pursue all of those passions at the same time. As a great bonus, I could also help people. I hope we can work together!

I write code 🤷‍♂️

Skills

This is a list of my favorite tools that I've worked with. Most of these I use every week, many I use every day.

I admit that this section might be overly detailed. I've just always loved looking at colorful collections. The rule here is: if I've used it for more than one week, and if it has a logo, then it's on the list.

Education

I am a completely self-taught programmer — I learned by watching YouTube, reading books and doing online courses. Still, I valued my formal education very much. It was very international, so I've been in a cosmopolitan environment for nearly all my life. Because of this, I could learn how to speak several languages and interact with people from all kinds of cultures.
