Real name: Dermot McNally. Mapping, mostly in Ireland since early 2007, when most of the country was empty space. I've also done some experimental mapping of pistes in Austrian ski resorts and some other Austrian mapping too.

OSM Projects:

* I imported GNS placename data for the Republic of Ireland (2007)
* GNS placename import for Northern Ireland (May 2008)
* Irish National Road Network completion
* Irish Border accuracy improvements

Real Life:

I'm co-found of Dobini, an OSM-based startup.
I'm co-founder and former CTO of Directski.com, the online Ski Tour Operator.
