Get in touch

The best way to reach me is email: tore@tn-data.se. A few lines are enough: what you are building, what is getting in the way, and what kind of help you need. You can write in English or Swedish. I'm open to new consulting assignments.

What I can help with

  • Authentication, identity and security in ASP.NET Core: OpenID Connect, OAuth and Duende IdentityServer. Reviews, implementation and coaching.
  • Hard .NET problems: I find the root cause by digging into the code, down to the framework source when needed.
  • Software architecture: DDD, CQRS, event sourcing and event modelling.
  • Azure for .NET teams: Azure development and Azure identity for .NET applications.
  • Technical due diligence: code and architecture reviews of large .NET codebases.
  • Agentic development: I help teams get started with AI in their software development, using coding agents like Claude Code in a way that works in real projects.

How we can work together

  • Consulting: assignments as a senior .NET developer or architect, and shorter specialist work such as reviews and coaching. More about consulting
  • Training: courses and workshops for teams, on-site or remote, in English or Swedish. See my courses
  • Talks: for conferences, user groups and internal events, usually 45–60 minutes, on-site or remote. See my talks

We can start with a short call, with no obligation, so I can understand what you need.
