I'm a London-based Engineering Lead; passionate about building simple, Test-Driven products and the teams to deliver them. Oh, and also about building the simple, Test-Driven, Open Source tools to power them 🙃. My latest coding passion is Kotlin, in which I co-created http4k, the Functional toolkit for building Kotlin HTTP applications. http4k, was featured in the ThoughtWorks TechRadar, in particularly being highlighted for it's dual focus on simplicity and testability. I'm also active as speaker at various international technology conferences and have also enjoyed developing and delivered Coding Dojos and full Training Courses, both in the UK and around the world.
