About Me

London, England Software Engineer — Economic Crime Prevention @ Lloyds Banking Group

I'm a Software Engineer at Lloyds Banking Group, building production AI systems that protect millions of customers from financial crime. I specialise in building agentic AI systems, full-stack development, and cloud-native development on Google Cloud Platform.

My expertise spans multi-agent orchestration, retrieval-augmented generation, real-time systems, and end-to-end product delivery across the tech stack. I focus on engineering systems that are: reliable, scalable, and performant.
