About Ryan
Reliable systems.
Curious by nature.
I’m Ryan Duffy. I work in site reliability at BT and explore applied AI through Rootweaver, an independent research platform I develop and operate.
Based in Ipswich, UK.

to AI systems
My background is in keeping networks and services working: tracing faults across distributed systems, restoring service and understanding why things failed.
That experience shapes the questions I bring to AI. What evidence should we trust? How do we know a retrieval result is useful? What happens when an agent gets something wrong?
Rootweaver is where I investigate those questions. It gives me a place to design experiments, connect systems and examine their behaviour over time.
How I work
I use AI agents extensively for implementation. I own the problem selection, architecture, controls, acceptance criteria, verification and operational outcome.
For me, the interesting work is turning an idea into something that can be tested, challenged and understood.
- Start with a question
- Define what we need to learn and what evidence would change the decision.
- Make behaviour inspectable
- Keep decisions, observations and uncertainty visible.
- Learn from operation
- Use failures and measured results to inform the next change.
Away from work
I enjoy anime and gaming. Gaming used to be my main hobby, but lately experimenting and building systems has taken over much of that time.
Rootweaver is a big part of that. It’s something I work on because I enjoy trying ideas out, seeing what happens and figuring out how to make things work.
