Technical depth. Business context.

I focus on turning complexity into clear, workable decisions.

For more than two decades I have worked across systems, data, search, cloud, security, observability and architecture. This breadth helps me read a solution from infrastructure and data models through to the people using it and the outcome the business needs.

I work with engineering teams and business stakeholders to explain options, risks and decisions in language appropriate to each context. I also share what I learn through articles and technical communication.
