Biography

I am Qiaolin Yu, a graduate student at Cornell University and Cornell Tech. My interests primarily focus on LSM-Tree based key-value stores, database systems, machine learning systems, and haircutting. Currently, I work as a research intern at Cornell Computer Systems Laboratory, advised by Prof. Udit Gupta. I also work closely with Prof. Zhichao Cao.

I also have amassed significant industry experience. I was a software engineer intern at Databricks in 2024 summer. Before that, I interned in the compute architecture team at PingCAP, the Azure Machine Learning team at Microsoft, the ByteHouse team at ByteDance, and the graph database team at Kuaishou.

I will graduate in May 2025 and am actively seeking NG opportunities related to quant, LLM, and systems. If you would like to chat, feel free to reach out. My resume is available upon request.
