Giới thiệu

Tôi là một Backend Developer chuyên về data engineering và business intelligence. Với kinh nghiệm xây dựng hệ thống xử lý toàn bộ vòng đời dữ liệu — từ ingestion đến visualization — tôi kết nối giữa dữ liệu thô và insight có ý nghĩa. Cách tiếp cận của tôi kết hợp giữa thực hành phát triển phần mềm vững chắc và tư duy hướng dữ liệu. Tôi quan tâm đến độ tin cậy của hệ thống, kiến trúc sạch và xây dựng giải pháp có thể mở rộng. Dù là API NestJS, pipeline PySpark hay report Power BI, tôi tập trung vào việc làm cho các thành phần hoạt động liền mạch cùng nhau.
