whoami

Full-stack web developer and Co-Founder at MST Software, a software company operating in the MMO (Make Money Online) market. Our products serve real users under real commercial pressure — live transactions, live money, live stakes.

At MST, my scope spans product direction, system architecture, feature development, and cross-team coordination. On the engineering side, I work TypeScript-first: Next.js on the client, NestJS and .NET on the server, PostgreSQL and MongoDB at the data layer.

Currently a third-year IT student at UIT (University of Information Technology, Ho Chi Minh City), specializing in Web Programming. Expanding into the Java ecosystem — Java Core → Spring Boot — alongside deepening my understanding of MMO business logic and systems design.



Philosophy

"Understand the system before you touch it. Ship only what you can defend."



MST Software — MMO Solution Technology

Co-Founder of a software company that builds specialized tooling for the MMO market. MMO is not a niche — it is an economy. Our products operate inside that economy: game account commerce, digital asset trading, fraud detection, and licensing infrastructure.

My role isn't limited to writing code. I participate in defining what we build, why we build it, and how it scales. Then I build it.


Responsibilities

Area Scope
Product Direction Define roadmap, feature scope, and tradeoffs based on market signals
System Architecture Design service boundaries, data models, and integration contracts
Feature Development Implement frontend, backend, and API layers end-to-end
Team Coordination Sync across engineering, business, and operations via Lark + Notion

Writing

I don't have a public blog yet — but I will. Topics I plan to cover: system design in production, TypeScript patterns, and building software for non-standard markets like MMO.

When it's live, it'll be here.
