I've been using KPhotoAlbum since around 2005. At that time I was doing mostly analog photography, which made KPhotoAlbum with its support for fuzzy dates an obvious choice - a choice that I am still happy with, today.

I started my "KPA carreer" because I thought that it was lacking the possibility to mark areas on the images and associate them with tags. With very much help of Johannes (who acted as a C++, Qt and KPA mentor for a long time and still does), I implemented this feature and worked on face detection and face recognition via libkface later.

My goal is to improve KPA with new features and fix bugs wherever I can (sadly, after all, I'm not really a C++ pro yet, and probably never will ;-). I want to contribute especially to the face detection and recognition parts and the map bindings, speaking of geotagging and querying the database by geographic coordinates.

In real life, I'm a dentist (yeah, I'm the only one here not making his bread with coding!), married to my lovely wife Barbara and dad of a son and a daughter.

I have been active in the FOSS world for over three decades, starting with work on X10 support for Emacs in the mid 1980's. I have worked in the computer systems industry since I graduated college in the late 1980's.

I'm an avid photographer. In the late 1990's, looking for a more economical way of creating large format prints, I bought a photo printer from a friend, found no Linux driver for it but did find Mike Sweet's print plugin for GIMP, from which I started the project that eventually became Gutenprint. Almost 20 years later, I'm still project lead for Gutenprint.

I'm a prolific photographer as well as an avid one. I photograph a lot of sporting events for my alma mater, and other events, and as a result have (currently!) about 275,000 frames totaling the better part of 3 TB. To manage those photos, I needed to find a good image management tool, and after trying several, settled on KimDaBa, which has since become KPhotoAlbum. I like the fact that it's fast and does not modify image files.

I have been a confirmed performance geek as far back in my computing career as I recall. Performance and scalability are essential for any kind of professionally-oriented workflow. As such, most of my contributions to KPhotoAlbum have been in that area.

Outside of work and photography (and the non-empty intersection of the two), my wife Manny and I enjoy the company of our little American Eskimo, Chloe.
