About Me

I'm Uong Thanh Tu, a third-year student at FPT University and a backend engineer passionate about system design and domain modeling. I build robust, secure, and scalable services primarily with Java and Spring Boot. I’m learning and applying Domain-Driven Design (DDD) to keep code aligned with business intent. My work emphasizes security (OAuth2, JWT), performance, and observability, and I routinely design systems that remain maintainable as they grow.

I also work with data platforms—relational and in-memory—namely MySQL, SQL Server, and Redis, to support high-throughput, low-latency backend workflows.

Java & Spring Boot

Building production-grade backend systems with Spring Boot, dependency injection, Spring Security, and performance tuning.

System Design & DDD

Architect scalable, maintainable services using Domain-Driven Design: bounded contexts, aggregates, and ubiquitous language.

Databases

Working with MySQL, SQL Server for reliable relational storage and Redis for fast in-memory caching / ephemeral state.

Security

Security-first development: OAuth2, JWT, threat modeling, and secure coding practices.

Performance & Observability

Optimizing throughput and latency while adding visibility (metrics, logging, tracing) to ensure reliability in distributed systems.
