Speaking and workshops

I speak about—and run workshops covering—big CSS, its architecture, and writing it in large teams on large products in a performant manner that scales. If you would like me to speak or run a workshop at one of your events, please drop me a line.

I also run private workshops, where I come into your offices and get hacking with your team. If you would like to organise one of these then fire me an email.
