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. To me, programming is an art form, a poem, a song, a dance.

But in time, it became something even more. 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 currently work as a back-end developer for FairFX, a foreign exchange company, and I still spend a lot of my time on community projects.

Testimonials

So far as I'm concerned, you write sane code, and you ask when you're stuck, and you listen to design ideas and then ask questions and then implement them.

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. I hope she continues to lend us her talents for a long time to come.

Cassie McDaniel, Webmaker UX Lead (Source)

Errietta has all the qualities of a great web developer in the making — 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.
