All of the things I have done professionally are proprietary and confidential, but here are a few side projects/hobby sites that I have done so you can see that I can, in fact, write code. Each has a credits page that lists the tools & technologies used.
My first site, started in 2003. Originally just my experiments with Unicode, but now includes file formats and physical media.
Online regular expression testing. Originally just a utility page on FileFormat.Info, but it got enough traffic to justify its own site. Now it has grown to support multiple flavors of regexes & a cookbook.
Printable label sheets. Another example of a utility page on FileFormat.Info that eventually deserved its own domain.
I needed consistently formatted logos for various projects (like RegexPlanet) and thought that others might find them useful.
Instant search for SVG logos with over 200,000 logos from over 100 sources. I made this after automating the searches I was doing for VectorLogoZone.
I realized the LogoSearch backend would work for things besides logos, so this is an instant SVG icon search using the same codebase.
Redirect a naked domain to the www version. Again, something I needed for myself and thought would be useful to others.
