Orzeszek Development is a collection of miscellaneous software that I’ve written, which I’ve released in the hope that someone will find it useful.

I’m a software engineer in Redmond, Washington. You can find my personal site here and find out more about me here.

The name of this site derives from the Polish language and was in the past intended to maintain my pseudonymity. It’s also an inter-lingual pun.

orzeszek n [IPA: ɔʐɛʂɛ̃k] — a small, hard-shelled, dry seed or fruit of some plants : diminutive of nut.
