Ben Orrin

Software Engineer · Brighton, UK

I build backend systems, and the platforms they run on.

I’m Ben, a C# developer with a platform engineering background. I’m currently building .NET software for Aviva with NETbuilder. Before that I worked on cloud infrastructure, CI/CD and observability as a platform engineer at Ground Control, and built APIs for clients like Lloyds Bank at Radical.
