DATA & AI ENGINEER

Building agent workflows and the data platform underneath them.

I'm Duyet — a Senior Data & AI Engineer. I focus on the foundational systems that make software work: data pipelines that scale, platforms that stay reliable, and AI agents that are actually useful. I build systems that are simple to operate and transparent about what they do — and I open-source most of what I build.

Deep in vibe-coding mode — most of what ships here is written alongside coding agents, with me steering.

Agent Sandbox on Kubernetes

I run Claude inside agent sandboxes on a home Kubernetes cluster. One consumes issue tickets into PRs, another triggers on Sentry webhooks to diagnose and patch runtime bugs. Here is the bigger loop, and where the new Kubernetes Agent Sandbox CRD fits.
