Welcome to dung87.io.vn

A collection of personal web projects — from MBTI tests and document lookup to point-of-sale tools.

2026-06-25 — Rebuilding the hub at dung87.io.vn with Astro + Cloudflare Pages, adding bilingual vi / en support.

About me

I'm a developer who likes building small, useful, and personality-driven web apps. Currently focused on React, TypeScript, and edge platforms like Cloudflare.

Outside of code, I write small tools, build quizzes, and try to turn half-baked ideas into real products.
