About
John Koster
and Stillat.com

My name is John, and I have over fifteen years of professional software development. I've worked on a wide range of projects over the years, from simple websites and critical government reporting applications all the way to high-performance telematics solutions. During my downtime, I enjoy working on open-source projects, writing posts on my blog, and contributing to the Laravel and Statamic ecosystems.

I started Stillat.com over a decade ago as place to share things I find interesting, or to host random side projects as I create them. I hope you enjoy your visit!

Blogging and Self-Publishing

I enjoy writing, and over the years I have published over 600 free articles on the blog and have self-published three books on Leanpub.

Some of my favorite things

Over the years, I have grown to love many remarkable frameworks, platforms, and products. Some of my all time favorites include Laravel, Statamic, Tailwind CSS, GitHub, and of course, PHP.
