Work & Experience

Purdue Center for Programming Principles and Software Systems (PurPL)

Research Assistant

2019/05 — 2019/08
  • Worked with Prof. Tiark Rompf on building Flare (OSDI’ 18, SIGMOD’ 18, & Spark + AI Summit 2018) - an accelerator for Apache Spark with native compilation on Scala front-end and support for distributed data processing, data pipelining and streaming.
  • Use Lightweight Modular Staging (LMS) framework to add distributing data processing support with Message Passing Interface (MPI) and outperform Apache Spark by up tp 10 times on standalone and computation-intensive workloads like TPC-H.

Microsoft Research Lab - Asia

Summer Intern

2018/05 — 2018/08
  • Designed and developed GraphView, a middleware and DLL library for key/value databases within one of Microsoft’s core Azure product - CosmosDB, in collaboration with senior researchers, the Intelligent Cloud and Edge Group and the Azure team.
  • Built the testing framework based on YCSB & TPC-C in order to benchmark GraphView and DBx1000 (SIGMOD’ 16), with optimistic concurrency control (OCC) algorithms.
