Software developer · Hanoi, Vietnam
Software that quietly
does the work.
I'm Quang — a developer obsessed with automation, system optimization, and agentic tooling. This is my digital workbench: code, home-lab engineering logs, and the tools I build along the way.
What I do
Ten years of building, from backend to agents.
AI-powered products
Image-generation platforms, organization-wide agent swarms, and GenAI adoption tooling — built with Claude, MCP, and RAG.
Backend at scale
Leaderboards handling 1,000 RPS across 130k DAU. .NET, Kafka, Redis, Couchbase — with the monitoring to keep it honest.
Home-lab engineering
Proxmox clusters, self-hosted services, and automation experiments — documented in the blog as they happen.
Workbench notes
Fresh from the workbench.
Redesigning This Site: From Terminal Goth to Editorial Cream
This site used to look like a hacker movie prop. Now it looks like a magazine that codes. Here's the design system behind the switch — and how an AI agent shipped it in one session.
Lab Census, Mid-2026: Eleven Containers and One Empty Chair
A headcount of everything running on the Proxmox cluster right now — taken live from `pct list` — including the container that quietly replaced Pi-hole while nobody was looking.
Giving My AI Agents a Shared Brain (Self-Hosted, Third Attempt)
How my Claude Code and Antigravity sessions ended up sharing one long-term memory — a self-hosted Hindsight instance on a Proxmox LXC — after two failed prototypes.
Let's build something.
Open to interesting problems in AI tooling and backend systems — Telegram is the fastest way to reach me.
