About OneByte

My name is Alex Hess and I'm the creator of OneByte. I created OneByte to serve as personal documentation of my work in technology. I found that many of the projects I worked on had valuable information. In hopes to preserve that information I decided to catalog and document my experiences here. OneByte is an evolving project and I hope it helps others as in the process. If it doesn't help you I hope you enjoy reading the nonsense. - yours truly


Check out the projects I'm working on, and have worked on. From design to server migrations.
