My name is Jonathan Feucht, and welcome to my home page! I live in Arlington, WA, and work as a professional electrical engineer. My hobbies include playing the piano and organ, photography, backpacking/camping, and riding my road bike.

This web page is to showcase some of my writings and web applications. I designed this web page after a Web Development course at the University of Washington, Seattle, with Marty Stepp.

It is rarely updated, so currently, all of the content on this site is old. To begin, select one of the links in the table of contents below.
