Hi, I'm Ian and I love Scala!

I am current working with Disney Streaming Services, whilst maintaining an opensource project in my spare time. Prior to that I introduced Scala to Net-A-Porter in 2011 and drove the company's investment in Scala over the following five years by providing beginner Scala workshops for near 100 employees, opensourcing as much as possible, speaking about Net-A-Porter's use of Scala at LSUG and Scala eXchange. By 2015 Net-A-Porter had 15+ Scala applications in production
