I build the platforms other engineers ship on, from Linux and Kubernetes to AI agents in production. At Mondu, a B2B payments company, my work spans the AI platform and credit risk decisioning. I own much of the delivery and cloud infrastructure.
- AI & agents — LLM orchestration, evaluations, guardrails, tracing, Model Context Protocol (MCP) and coding-agent skills.
- Platforms & production — Kubernetes, Terraform, GitOps, observability and incident response.
- Architecture & products — Go services, distributed systems and applications from backend to frontend. Developer tools such as devbox, used by my colleagues.
I'm building coagent for unattended coding tasks and Zoebox for local databases on macOS without Docker. My go-ext4fs and cloudiso libraries build ext4 and ISO 9660 images in pure Go.
I also built tripflare for security testing, including AI agents: it records DNS lookups and HTTP requests to canary URLs.
I built two Kubernetes components in Go, published under my employer's organisation: a pod identity webhook for IRSA-style identity outside EKS through OpenID Connect (OIDC), and a kubelet credential provider for pulling images from Artifact Registry with federated, short-lived credentials.
Day to day: Go, Python, JavaScript, Linux, Kubernetes, Terraform, Kafka and PostgreSQL.
