About me

A developer working on databases and systems, based in Hefei, China. Mostly C++ and Rust, with an interest in storage engines, query execution, and the training and inference stacks behind language models.

A few things I’ve worked on:

  • CSCC-DB / Rucbase 2024 — National Collegiate Computer System Capability Challenge, database track: 2nd of 325
  • RMDB 2023 — the previous year’s edition of the same contest: 21st of 382
  • KDD Cup 2026 — DataAgents track: 9th of 703
  • ipatool-rs — an App Store CLI written in Rust
