I’m a Senior Developer Relations Engineer at Google, based in London, specializing in Go, Data Engineering, and AI Agents. Over the past two decades in software engineering and architecture, my focus has been building reliable, high-performance systems and helping developers master modern tooling. Prior to joining Google, I was a Google Developer Expert (GDE) in Go and Google Cloud Platform.
My current work centers on AI-assisted engineering and agentic architectures—exploring how generative models, the Model Context Protocol (MCP), and the Agent Development Kit (ADK) integrate into production software workflows. I advocate for disciplined vibe coding: pairing classical engineering rigor, automated verification, and sound architectural design with AI-augmented development.
Outside of work, I maintain open-source developer tools, play retro and modern video games, and pet every friendly cat I meet on the street.
