I don't think there is an easier way to put this than: Open source is my jam!
This list below are some of the open source projects I am currently working on.
An "Entity Framework"-like interface for the MongoDB .NET Driver. What started as an internal project for my business, it has become one of my larger open source libraries.
A simple but powerful "polite" web crawler library for .NET developers. Doesn't have dashboards or require a database - it keeps it simple.
An efficient multi-layered caching system for .NET projects. Inspired from a blog post, this has become a popular caching tool.
An extremely optimized .NET Levenshtein Distance calculator. Uses the various techniques I cover in my Levenshtein Distance blog posts and then some.
Robots Exclusion Tools
A .NET library to parse "robots.txt" - used by Infinity Crawler and my Sitemap Tools libraries. It makes it easy to check whether a URL is allowed to be crawled or not.

Using CPU-specific instructions for even more performance
