About

Justin Poehnelt

I'm a Developer Relations Engineer at Google, focusing on Google Workspace. My work involves creating tools and supporting the open-source community.

Before Google, I had the opportunity to work with geospatial data at Descartes Labs and the US Geological Survey.

When I'm not coding, I'm usually running long distances in the mountains of Colorado.

Exploring Apps Script CacheService Limits

A deep dive into Apps Script CacheService limits. I verify key/value constraints and uncover the undocumented FIFO batch eviction policy at the 1000-item limit.

Google Drive Picker TypeScript - Types Updated

Last week I submitted a pull request to the DefinitelyTyped repository for the Google Drive Picker API. Not a big deal in itself, but these types are generated from the same source as the Google Drive Picker reference documentation and should be more correct and consistent than the community types that were previously in the DefinitelyTyped repository.
