About Me

Passionate about building products that live on the internet.

Hello there! My name is Nikola, and I am passionate about creating things that live on the internet. Specifically, I am interested in web development and design.

I first became interested in web development in 2018 when I decided to try my hand at creating a website with WordPress. This experience taught me a lot about HTML, CSS, and SEO practices.

Since then, I have had the privilege of working with both a huge corporation and a couple of startups. As a senior software engineer, I am constantly striving to improve and grow my skills.
