My name is Jarrett and I am happy that you have found my blog! I hope that it's easy to navigate and that you explore some of my posts.


I am a Washingtonian. During the week I spend most of my time on my laptop programming or learning about computer things. Sometimes on weekends I'll hike, and a few times a year I like to go backpacking. I post hiking galleries and backpacking recaps in the Nature section.

Sometimes I'll listen to a good podcast, read a book, or watch a video that inspires a blog post about progress, self-improvement, or anything interesting. Those posts end up on the Progress page.

I do freelance tech and programming work, so I may write about a new technology or project on the Tech page. To find out more about my services you can visit my business site.

If you have questions or comments about the site my email can be found at the bottom of the page!

Python FastAPI: API-First

This article does not deal with Python or FastAPI, per se. Instead, we'll talk about why we wanted to create an OpenAPI spec in the first place. With the spec, we can set up mock APIs and documentation. Below is an example of how I was able to integrate the API into my backend CMS and frontend React
