Always Learning

I started programming because of a strong curiosity in the world of technology. I put time into quenching that curiosity with new technologies and more understanding of the programming languages I currently use.

I left the golf industry because I saw so many interesting and exciting things in tech. I didn't know where software would be in ten years, but I knew that if I stayed in golf I'd still be answering the phone and fixing slices in ten years.

[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. [...] a great addition to any team because he thrives as an independent contributor as well as an amazing team player who teaches everyone along the way.

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

Amazing skills! Very analytical, knowledgeable, and able to communicate with a non-techie. Super rare find. [...]

He is very good with communication, delivery on time and providing valuable suggestions. I'll definitely hire him again very soon and would highly recommend.

Jarrett was a pleasure to work with. Great attention to detail and completed the job on time and on budget. Would highly recommend!

[Jarrett] is very efficient & helped us resolve multiple issues in a short time frame by understanding project requirements very swiftly.

Performance issues may have never crossed your mind building your first React application. There were much more pressing issues to figure out. Furthermore, you weren't quite sure how to check performance. However, as the application grew in complexity, it became apparent that some

Continuous Integration on Github with FastAPI and pytest

This article discusses another Github Action that targets unit testing and installing dependencies when developers create pull requests. Pull requests let maintainers review, test, and decide if code should become part of the Git repository. Fortunately, we can save ourselves time when reviewing
