Hi! My name is Attila Beregszaszi and I work as a JavaScript developer. I used to work a lot with Drupal too. I’ve been making websites for quite a while now. My areas of expertise are front-end performance tuning and building complex web applications.

I am based in London and work on a contract basis. You can reach me using the links at the end of the page.
