About Me

Trí Decent

Hi, I'm Anh Trí, a Fullstack Developer with an interest in building web applications that serve people well, and I'm always eager to grow and learn from others.

My Journey

From learning the fundamentals to building full-stack applications.

I started with the fundamentals of web development and gradually moved from JavaScript and basic web applications into C#. Working with C# introduced me to a more structured approach to software development and gave me a stronger foundation in SOLID principles, design patterns, and maintainable code.

That experience shaped the way I approach software today. I tend to favor clear boundaries, immutable data, composition over inheritance, and keeping business logic separated from infrastructure concerns.

I later moved into the TypeScript ecosystem, focusing on React and Next.js and building increasingly complete full-stack applications. My current work is centered around areas such as authentication, authorization, multi-tenancy, subscriptions, and application architecture.
