I am a hands-on, senior engineer with leadership experience. I specialize in building distributed backends, APIs and data-pipelines; delivering technical excellence with AWS. I have a keen sense for enablement, focusing on developer workflows and tooling to drive productivity across the stack.

I am passionate about F# because of its power to produce correct & concise code. I use functional programming principles at the macro-level, resulting in event-driven architectures that promise resilience and flexibility. I am comfortable designing and working with cloud-native systems, and often found by the whiteboard or coffee machine.
