Hi, I'm Đạt, a fullstack developer and designer in Hà Nội, shipping software since 2018.

What I build and keep free:

- AgentPet, open-source macOS menu bar pet that watches your Claude Code, Codex and Gemini CLI sessions

- tools.datnt.dev, 100+ privacy-respecting dev tools that run entirely in your browser. No ads, no tracking, ever

- PlugTalk, a macOS USB manager with sound packs, per-device controls and external display detection

- datnt.dev, my portfolio, a miniature desktop OS in the browser

Day job: Senior Fullstack and Shopify expert at Demetio, building e-commerce and AI products for Japanese clients.

Every coffee here goes back into hosting, new tools, and the next open-source release. Thanks for keeping the lights

on.
