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.
A Kanban Board My AI Agents Actually Use
A two-person kanban for Ray & Toản that runs on a single Cloudflare Worker with D1 — and that my AI agents edit directly through SQL because the browser UI is for the humans.
From 15 Minutes of Hand-Editing to 100+ Videos a Day
The full evolution of a YouTube content pipeline: script generation, batch image creation, SRT translation, and rendering at a scale where one human had to stop being the bottleneck.
Reverse-Engineering a Tool That Was Too Fast
We bought an AI image tool that ran suspiciously fast and showed no browser history. I spent weeks trying to figure out how — network sniffing, decompiling a Hermes-built client — and never fully did.
Let's build something.
Open to interesting problems in AI tooling and backend systems — Telegram is the fastest way to reach me.
