I write software and web applications in a number of languages, including Python, Java, Ruby, and C#.
I design websites - just look at this one.
I design, implement, and use databases for web applications and statistical analysis.
A Python bot that protects the Stack Exchange network of websites from spammers. There's also a web dashboard, which is a Ruby on Rails web app.
A C# WPF desktop client for the Stack Exchange network. Still a work in (slow) progress.
One of my early dabbles in Rails. An address book app with strong encryption as a feature.
