Profile Picture

Sam Foster
UX developer & JavaScript Engineer


This dates back to ~2010. It is here for fun and as a historical record only. See my profile on linkedin for a slightly more up to date resumé.


I have over 15 years professional experience in web and user-interface development, working in a deadline-driven, budget-conscious team environment. I bring a deep knowledge of client-side web technologies to the product design and development process.

I can wear architect, developer, presenter, mentor or trainer hats. In recent years I have been focussing on JavaScript, in particular building on and with the open-source Dojo Toolkit project.
