Ruby developer living and working in London. For many years has been learning, blogging about and experimenting with event sourcing and surrounding patterns across different architectures and languages. Author of two experimental Ruby libraries presented at wroclove.rb 2026: Cidurial (reactive web toolkit built on Falcon + Datastar) and Sourced (event-sourcing library with deciders, projectors, reactors and correlated workflows). Has previously given talks on the actor model. Acknowledges having essentially zero production experience with event sourcing — he explores the patterns and publishes the results on his website.
