Hi there 👋

I'm Andy Grove, a software engineer specializing in distributed systems and query engines. I am the author of the book How Query Engines Work.

Career

I work for NVIDIA where I contribute to the RAPIDS Accelerator for Apache Spark, which is an open source plugin that provides GPU-acceleration for ETL workloads, leveraging the RAPIDS cuDF GPU DataFrame library which uses the Apache Arrow memory model.

Open Source

I am a PMC member and active contributor in the Apache Arrow project, where I have made the following donations:

I am also the original author of the sqlparser-rs crate.

Hobbies

I occasionally work on hobby projects involving digital electronics, microcontrollers, woodworking, and similar skills. Some of my projects have been featured on popular "maker" web sites.
