About Ratko

Hi, I am a 24 years old Full stack web developer based in Stockholm, Sweden. I started with web development in my senior year of high school doing mostly front end. Over the years, I gained a lot of experience building websites, WordPress themes and JavaScript web & mobile apps.

Currently, I work as a Frontend developer at Studi here in Stockholm City.

When not writing code, I really enjoy learning new stuff, cooking delicious food, playing with my cat "Cile" and lifting heavy weights :).
