  about training/

  Workshops, live-coding sessions, and conference talks on AI-augmented development, functional programming in .NET, type inference, and language-/DSL-design. Delivered in-house or remote.

  about consulting/

  Audits, architecture reviews, and sparring for teams deciding how (and whether) to bring AI into their engineering process — or whether F# / a functional architecture would pay off.

  about engineering/

  Hands-on work on AI pipelines, developer tooling, typed templates, reactive UI frameworks, and embedded creative-coding systems. I say no to generic CRUD. I say yes to problems where ten years of compiler and FP habits actually matter.

1. Composition beats objects. Lego, not Playmobil. Pure functions compose forever; object hierarchies are dead ends.
2. Syntax should match how you think. If a language makes you fight notation to express intent, it’s the wrong language.
3. Types make code obvious. Hindley-Milner inference plus structural records replace paragraphs of documentation.
4. AI drifts — discipline pays. Reproducible AI output comes from small tools, tight specs, multi-turn loops, not heroic prompts.
5. Build the tool, don’t buy the SaaS. Three hundred lines of code that do exactly what you need beat any feature-bloated platform.
