I am currently an engineer at OpenAI infra team. Previously, I co-founded OtterTune, an AI-powered database optimization startup. Before that, I worked with Prof.Andy Pavlo at the Carnegie Mellon database group on the OtterTune research project. I have spent several years in optimizing Postgres for many customers with both domain knowledge and machine learning.

I spoke at PostgreSQL Conferences in the past including PGConf Asia 2020, PGConf Asia 2021, PGConf Silicon Valley 2023 and Postgres Conference 2024.
