Rockstar🎓
Top SchoolZhe-You (Jason) Liu is a backend-focused software engineer and senior CS student from Taiwan with five years of hands-on experience in distributed systems and production services. An Apache Airflow Committer who has contributed 100+ PRs and reviewed 300+ more, he’s driven significant stability and performance improvements—such as a 10x memory reduction when reading webserver logs and refactoring multiple core REST endpoints from Flask to FastAPI. He’s shipped features and fixes across large-scale open source infrastructure (including a bugfix for PythonOperator handling DAGs with hyphens and a public list-tags API) while interning on backend teams at Microsoft and Appier. His work spans backend refactors, auth for core APIs, resilient async workflows, and test-flake fixes for Kubernetes and E2E suites, showing both product impact and engineering rigor. Now at Astronomer, he continues to bridge OSS leadership with production engineering, often tackling subtle reliability and API ergonomics issues that others miss. He pairs strong TDD and automation practices with a knack for simplifying complex system behaviors into robust, maintainable components.
