Work Experience

Backend Web Developer Intern at Qihoo 360
January 1, 2023 - January 1, 2023
Contributed to the development of STARK, Qihoo 360โ€™s internal Data Middleware Platform supporting system management, data asset cataloging, permission control, and task scheduling. Designed and implemented Spring Boot microservices (user management, data source registry, access control) with REST API contracts and data models. Integrated MyBatis and MySQL to build reliable, testable service layers; optimized queries and schema usage for high-volume data operations. Supported large-scale data workflows across Hive/TiDB/MySQL by exposing service endpoints for asset cataloging and report automation (script/SQL-driven). Hardened job scheduler with log-driven debugging and logic refactoring, reducing recurring failures by 40% and improving on-time task completion. Collaborated with UI/analytics/product to align API payloads and SLAs; authored onboarding docs and runbooks to streamline adoption and operational support.
