What I'm looking for

I'm looking to build clean, maintainable cloud-native software that delivers real business value, while taking ownership, contributing technical input and supporting collaborative teams in fast-paced Agile environments.

At ASOS, I helped launch ASOS.World to UK customers, supporting more than 500,000 sign-ups in its first year and later helping grow sign-ups beyond one million through automatic customer enrolment. I build the infrastructure, APIs and event-driven services behind scalable customer experiences using C#, .NET, Azure, Kubernetes, Cosmos DB and Service Bus.

Previously, I delivered production IoT and payment solutions at McDermott Group, including work supporting more than 600 devices across five Glasgow tower blocks, and built web, microservice and cloud solutions for Canada Life and BP. I enjoy clean, maintainable software, mentoring developers, code reviews and taking ownership in collaborative Agile teams.
