The Philosophy

I've been building things since 2011 — container runtimes from scratch, multi-agent AI systems, and 15+ years of making Go do unreasonable things.

Currently serving as Staff DevOps Engineer at Automattic, I work on infrastructure, reliability, and developer experience for a fully distributed team. I optimize distributed systems and lead cloud-native transformations with an obsession for precision, performance, and long-term maintainability.

Beyond the IDE, I treat software as structural engineering: strong types, functional paradigms, and deterministic environments. I automate the mundane and architect what is next.

Build Your Own Container Runtime in Go

2026

Tue 27th October, 4:30 pm – 5:15 pm

ContainerDays Singapore • Singapore

We all run containers. Most of us couldn't build one. In this hands-on workshop I strip away the "magic" and we build a minimal container runtime from scratch — in Go, live — using nothing but the Linux kernel primitives that make isolation possible. No Docker, no runc.

Building a Container Runtime from Scratch

Containers often feel like magic: run a command, and suddenly your application is isolated from the rest of the system. But what is actually happening underneath?

From veth Pairs to Services: The Secret Life of Container Packets

2026

Thu 12th February, 4:55 pm – 5:30 pm

ContainerDays London • London

Containers make networking look simple: kubectl exec into a pod and curl just works. Under the hood lies a fascinating stack of Linux features — network namespaces, veth pairs, bridges, and iptables — that power connectivity in standalone Docker and Kubernetes pods.
