Backend Engineer · Data Platform
I work on data collection and integration systems with Java and Spring Boot, with a focus on data pipelines, workflow orchestration, and database performance.
I also contribute to Apache SeaTunnel, turning problems found in real-world data processing into upstream fixes and improvements.
I enjoy contributing to open source projects.
Currently, I'm contributing to Apache SeaTunnel.
