I wrote code for 25 years. The last 138,000 lines, I didn't.

I help companies integrate AI reliably into their own software development.

AI tools increasingly take over the implementation. The value moves to where it stays demanding: describing precisely what should be built and why — and structuring knowledge so machines can work with it reliably. That is my field.

What I believe

Software development is changing fundamentally. AI tools take over the pure implementation — faster, cheaper, and increasingly in teams without classical programmers. What remains is the genuinely hard part: clarifying what should be built, and why. And capturing domain knowledge so that AI assistants work with it reliably instead of guessing.

I built software for a quarter of a century — and over the past few years I rebuilt my own way of working from the ground up: I write specifications, schemas and knowledge structures; agents write the code. That experience is what I pass on — to teams with their own development as much as to small companies that want to become independent of their agency.

What I work on
01

AI integration into development

Helping teams adopt AI tools productively and reliably in their software development — including teams without a classical programming background.

02

Specification & domain knowledge

Preparing domain and system knowledge so AI assistants can genuinely work with it. Structure instead of prose — verifiable, versioned, kept current.

03

AI-assisted implementation

Architecture, toolchains, reviews: modern, heavily AI-assisted development — grounded in more than two decades of full-stack practice.

No in-house developers?

Not every company has developers — many depend on their agency for every small change. For exactly this case I am currently developing a method: rebuilding or migrating small web projects AI-assisted, with everything in your own hands from day one. By the end, you handle most everyday changes yourself — and know exactly when to call me.

So that nothing breaks along the way, the guardrails are built in from the start: protected version states, automated checks before anything goes live, every state recoverable. And because everything runs on your own accounts, the project belongs to you from day one — including a structured knowledge base your AI assistant can work with reliably.

Memstead — living proof

Memstead is my open-source project: a durable, typed memory for AI agents. Knowledge lives as plain markdown in a git repository — readable by humans, diffable in review, with no database and no vendor lock-in. Agents read and write it through a schema you control, enforced on every single write.

Above all, Memstead is my demonstration piece: this is what software development looks like when you run it consistently AI-assisted — with clean specification, enforced schemas, and a human at the helm. And the proof is not a claim: every line, every commit, every decision is publicly verifiable in the repository.

Let's talk.

My consulting practice is still in formation — until then I'm happy to connect and trade notes: on AI-assisted development, on Memstead, or on hands-on experience. Write me — short and informal is perfectly fine.
