Work Experience

• Jun 2026 – Present: Ph.D. Software Engineer Intern, Multimodal Data Infrastructure
  • Uber Technologies, Inc., Sunnyvale, CA
  • Built the metadata catalog layer for a multimodal data platform, extending Apache Gravitino to provide unified catalog, schema, and table abstractions over text, image, video, and vector-embedding modalities.
  • Enabled the Lance SDK to use Gravitino as its catalog backend by implementing the Lance REST namespace and table APIs.
  • Designed access control and metadata-integrity mechanisms covering authorization at catalog, schema, and table granularity, and auditability of metadata mutations.
  • Contributed fixes upstream to Apache Gravitino, including a metadata-store schema correction that eliminated cross-table index-name collisions.
• Jul 2020 – Jan 2021: Research Intern, IoT Security and Knowledge Graph
  • Beijing Key Laboratory of IoT Information Security, Chinese Academy of Sciences, Beijing, China
  • Supervisor: Prof. Limin Sun
  • Built crawlers collecting IoT device, industry, and open-source project metadata; constructed a dataset of 56,000+ IoT-related open-source projects across 176 categories.
  • Developed an NLP-based pipeline combining fastText with custom feature-based algorithms to infer device ownership industries from device descriptions.
