I'm Errietta Kostala and I'm a full stack developer...
with a passion.
Ever since I was a teenager, I knew I wanted to be involved in programming. I spent countless hours working on my own projects, learning more and more and becoming more and more fascinated.
As I started getting involved in freenode, Mozilla, and other open source projects, it became a way to be part of a community - I could network, make friends, and meet people that would be with me for the rest of my life.
It then became clear to me - I didn't just want to follow my passion of programming. I wanted to teach others what I knew. And I wanted to keep supporting Open Source projects and helping others.
For this reason, I studied Web Technologies at the University of Huddersfield - so that I can learn even more about what I'm passionate for, and I did an internship for Shadowcat Systems - a small company in Lancaster that holds open source and community projects very dearly.
I'm an ex-employee of FairFX (or as I call it FairF-eX) and I currently work as a software developer for Zoopla , and I still spend a lot of my time on community projects.

I have a sneaking suspicion this woman is going to be scary good in a few years.Matt Trout, Shadowcat Systems Technical Director.
We get a lot of contributors but it is not every day someone so seamlessly integrates with the entire team. I went away on vacation and when I came back Errietta was an integral part of our work environment – a powerful presence on IRC, at our video demo call and on GitHub.Cassie McDaniel, Webmaker UX Lead
Errietta has all the qualities of a great web developer — she learns quickly, values feedback from both engineers and designers, and cares deeply about sharing her knowledge with others. I'm always impressed by how quickly she's willing to jump into a new code base and effectively solve problems.Kate Hudson, Webmaker Developer
