In my spare time when not working as a software developer, I contribute to a couple open source projects that I am quite proud of:

• ELMAH (Error Logging Modules and Handlers) is an application-wide error logging facility that is completely pluggable.

• URL Rewriter a .NET module which mimics the Apache mod_rewrite syntax for support in IIS and Casini

• Fluent Cassandra a .NET client for accessing the NoSQL Apache Cassandra database.

Oh yeah and I also wrote a book:

• Co-authors of ASP.NET MVC 1.0 Website Programming: Problem - Design - Solution published by Wrox and released in June 2009.
