An Open source buff, I have been deeply involved in Web mapping for over a decade. Contributor to many projects, I'm focusing on Web application technologies mainly around MapServer.
I'm a co-founder of Mapgears:
Members of Mapgears' team have been active for over a decade in the development of the MapServer Web mapping engine and related open source technologies of the Open Source Geospatial Foundation (OSGeo). Mapgears offers professional, yet personalized services to assist application developers and integrators who made the choice of MapServer and other OSGeo technologies such as PostGIS, GDAL/OGR, OpenLayers, GeoExt and GeoPrisma.
Mapgears counts as part of its Technology team some of the main developers of Mapserver and related open source technologies, who in turn have access to an international network of trusted partners which includes the majority of the other developers of those same software packages.
Whether you already have or not your own development team, know that Mapgears can join you in order to help you serve your customers and users better.
