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.

AI-era engineering,
built on fifteen years of
functional craft.
I help technically ambitious teams build AI-assisted workflows that stay reproducible, maintainable, and honest about their limits. I bring F#, .NET, and compiler-level thinking to problems most people try to solve with prompt templates. You get craft, not hype.

Structure wins — in types, and in AI workflows.
Vibe coding, without the “vibe” excuse.
I build tools. Train teams. Ship software that survives the quarter.
[01] Services
Three screens. Equal weight.
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.
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.
[02] Featured Projects
Things I’ve built. Still running.
PXL Clock
A 24×24 programmable LED display you code in C# or F#. VS Code extension, hot-reload simulator, over-the-air updates.
pxlclock.com
· code RONALD for €25 off
FsHttp
A hackable HTTP client for .NET. Reads like .http
files, scales to any edge case. 499★ on GitHub,
128 dependent packages.
TypeFighter
An experimental language built around an inference-first, structural type system: records match by shape, set-theoretic unions, minimal annotations.
TheBlunt
A one-file recursive-descent parser-combinator library for F# and Fable. Small surface, serious power.
Trulla
Templates that are type-safe at compile time. Ships as an F# Type Provider, a C# Source Generator, and a Node.js CLI.
[03] Theses
Five cartridges. Load and run.
Composition beats objects.
Lego, not Playmobil. Pure functions compose forever; object hierarchies are dead ends.
Syntax should match how you think.
If a language makes you fight notation to express intent, it’s the wrong language.
Types make code obvious.
Hindley-Milner inference plus structural records replace paragraphs of documentation.
AI drifts — discipline pays.
Reproducible AI output comes from small tools, tight specs, multi-turn loops, not heroic prompts.
Build the tool, don’t buy the SaaS.
Three hundred lines of code that do exactly what you need beat any feature-bloated platform.
