About

I am a professional web application developer and blogger in Spokane, WA. I graduated from Eastern Washington University with a degree in Business Administration and worked as an Assistant Golf Professional in Washington and California before switching to a career in technology. My area of expertise is front-end development.

I've worked successfully with clients from the East Coast of the U.S., Europe, and halfway around the world in India. My articles have been published on multiple blogs covering backend development, API testing, continuous integration, and user interfaces.

TESTIMONIALS

[Jarrett] is the best developer I have ever worked with. Since day one, he not only delivered high quality code, but improved everything about our application and overall team. He consistently exceeded our expectations by suggesting and then implementing improvements that enhanced user experience and backend efficiency.

Jarrett was an excellent addition to our team. Did a great job on React development, self managed and very easy to work with.

Check If Google Credentials Are Valid

This is a short post on checking if Google OAuth2.0 credentials are valid in a Python—FastAPI—application. The backstory is that I have an application that is in "test" mode in Google Cloud Projects. Therefore, the credentials expire every seven days, and I'm not sure when I'll get around to
