What I actually work on

Not a list of everything I have heard of - the stack I have shipped and maintained in production, mostly inside codebases somebody else started.

Back-end

Where most of the fifteen years went. Business applications, APIs and the data layer underneath them.

Front-end

React and Next.js in TypeScript, or Blazor when the team would rather stay in C# end to end.

Applied AI

Language models inside business tools, when the context warrants it. A tool, not a mission statement.
