About

I'm a technology leader with over a decade of experience building scalable systems across financial services. My career has taken me from system administration and microservice development through to leading enterprise-wide Kubernetes platforms, and now architecting generative AI solutions at scale.

I've worked across major institutions including Morgan Stanley, Barclays, and JP Morgan Chase, building expertise in containerization, cloud platforms, observability, and most recently RAG systems, multi-agent pipelines, and LLM integration.

I believe the best technical leaders never lose touch with implementation details. I stay hands-on and lead from the front, whether that's debugging a production issue or designing a new platform architecture. I'm passionate about emerging technologies and enjoy tackling complex problems with pragmatic, well-crafted solutions.
