about

I’m a Principal Systems Architect with a background in distributed systems, cloud-native engineering, and large-scale software architecture. I’m currently exploring how AI-native systems change the way we think about orchestration, runtime behaviour, observability, and stateful execution in production environments. This blog is a place to document ideas, experiments, and architectural observations around AI systems, platform engineering, distributed runtimes, and modern software architecture.

  • What Happens When C4 Meets a Capability Language?

    An experiment in combining structural and behavioural architecture models for AI-assisted reasoning. Why combine C4 and DCL? Architects rarely work with one complete representation of a system. A C4 model can show systems, containers, relationships, and dependencies. It is excellent at answering questions such as: But structural diagrams do not always explain the business behaviour…

  • AI Needs Better Architectural Representations

    Ask an LLM to modify an existing system, and it will often produce convincing code. But ask it questions such as: And the answers quickly become uncertain. The problem isn’t necessarily the model. The problem is the representation. We Optimised Architecture For Humans, Not AI Discuss how current architectural artefacts evolved. Current architectural artefacts evolved…
