I build software
that thinks.
AB Systems is my research lab. I take real problems, find the solution that fits — AI agents are one tool among many — and run it in production so you can see how it holds up.

- Next.js
- React
- TypeScript
- Node.js
- Python
- FastAPI
- LangGraph

What I'm working on
Start from the problem — pick the right tool.
Sometimes the answer is a team of AI agents. Sometimes it's retrieval, a pipeline, or a well-made tool. Each one here is built and running, so you can see how it holds up.
Decisions that need more than one point of view
A panel of specialists that recommends, critiques, rebuilds and re-scores the work round after round — and only stops when it genuinely converges.
Approach · Iterative multi-agent refinement
Try itResearch you can actually check
Every claim tied to a source that was really read, and an honest list of what couldn't be verified.
Approach · Agentic web research
Try itFinding the one passage in half a million
Layered retrieval over a library of public-domain books: narrow by book and chapter, search by keyword and by meaning at once, then rerank — every answer cited to the exact passage.
Approach · Advanced retrieval at scale (RAG)
Try itPutting an AI agent on a real desk, safely
A factory that turns a team's own procedure into an agent — derives what can go wrong, writes and runs the proof, and keeps a person in charge of every case.
Approach · Agent factory with evals and guardrails
Try itPublishing that never sleeps
A news platform that reports on markets around the clock, with an automated editorial pipeline doing the legwork.
Approach · Automated content pipeline
See it liveLetting others build without code
An open-source visual studio: design a workflow, watch it run, export a project you own outright.
Approach · Open-source tooling
See it liveProjects
Everything I've built — and keep running.

Hiring Panel
AI project · liveSix specialists work your CV round after round — scoring, arguing, rebuilding — until they agree it's ready

Research Agent
AI project · livePlans its own web research, judges its own evidence, cites every claim

The Library
AI project · liveAsk anything about half a million passages of classic books — and see exactly how the answer was found

The Teammate Factory
AI project · liveDescribe a job in your own words — the factory builds an AI teammate for it, proves it, and keeps a person in charge

Crypto Newsroom
ProductAn AI-run crypto news platform that reports on markets around the clock: a website, a mobile app and the automated editorial pipeline behind both — stories drafted, edited and illustrated by models, with live market data and a house illustration style.

Bitcoin Bull/Bear signal
ResearchA mechanical trend indicator for Bitcoin's 1-week chart — pure rules, no AI, no discretion. Every weekly close is labelled bull or bear, flips are rare by design, and it is back-tested on every weekly close since 2017. Think of it as a "money line": one line that says which side of the market you want to be on. I share the research and findings; the rules themselves stay private.

Crew AI Studio
Open sourceA no-code studio for CrewAI: design agent crews visually, run and observe them live, then export a portable Python project you own completely.
About
A lab for solutions
that actually run.
I'm Arthur. AB Systems is where I work on solutions to real problems and find out whether they hold up outside a demo — with real inputs and real limits.
I start from the problem, not the technology. Sometimes the right answer is a team of AI agents; sometimes it's retrieval, an automated pipeline or simply a well-made app. Whatever it is, it runs in production here, and the AI projects show their reasoning as they work — including the parts that go wrong.
When something turns out to be useful beyond an experiment, I ship it — like Crew AI Studio, which is open source. Based in the Netherlands.
