About

I build things people actually use.

I'm a third-year IT student at UTH — but my projects don't look like coursework. Tutor Pro started as a tool I built to manage my own tutoring business. It grew into a full EdTech platform with WebRTC live rooms, AI feedback, VietQR invoicing, and a real-time notification engine. Core-complete and running in production.

Simultaneously, I'm leading a 6-person team building a microservices platform for flood rescue coordination — responsible for architecture, infra setup, CI/CD pipeline, and sprint management via Jira. Two production-level projects, running in parallel, year 3.

Backend is my core — I care deeply about API design, system architecture, and performance. I also handle frontend independently with Next.js, which lets me deliver complete features without blocking on a separate team.

Let's build something real.

Open to backend internship and fresher roles in 2026 — Vietnam or remote. If you're building something interesting, I'd like to hear about it.
