I'm a Senior Java Developer based in Thu Duc City, Ho Chi Minh City, Vietnam. Currently working at MWG (Mobile World Group) — the largest retail corporation in Vietnam — where I lead backend development and build scalable microservice systems.

My expertise spans the full backend stack: from designing CQRS/ES microservices with Spring Boot, processing millions of events through Apache Kafka & Flink, to optimizing query performance with Apache Kudu & Kylin.

I'm passionate about learning new technologies and am constantly expanding my skills in cloud infrastructure (AWS/GCP), data engineering, and distributed systems.
