I've been a core developer to a number of widely used applications and libraries over the past 20 years or so.

I'm probably most famous for my work on MIME parsers (such as GMime), IMAP, and anything mail related (I'm responsible for a lot of the mail code in Evolution) and for my work on the Moonlight project.

These days I'm working at Microsoft on Visual Studio for Mac.

My free time is spent working on MimeKit and MailKit, yet another set of email libraries... but this time written in C#.
