I build robust backend engines that scale.
Hi, I'm Tran Quang Thong. A Software Engineer designing high-performance RESTful APIs, optimized data architectures, and clean backend systems.
About Me
Backend Engineer with hands-on experience designing and developing production-grade RESTful APIs using NestJS, TypeScript, .NET, MongoDB, and SQL Server. Experienced in building high-performance e-commerce, logistics, and digital transformation systems with role-based access control, complex query optimization, and secure third-party integrations.
I am dedicated to writing clean, testable code and structuring scalable databases. I enjoy collaborating with mobile and frontend developers to design clean API contracts and deliver unified products.
My Core Engineering Principles
Clean Architecture
Implementing Domain-Driven Design, CQRS, and Repository patterns to keep systems decoupled and modular.
Performance First
Optimizing queries, indexing databases, caching with Redis, and writing DRY, non-blocking asynchronous code.
Security & Safety
Enforcing Role-Based Access Controls (RBAC), validating inputs, and applying secure authentication flows.
