David Erill
Barcelona, Spain
I've been developing GIS software and designed geospatial databases plugins and geospatial analysis tools for the major GIS softwares. I've a lot of experience in most of the main databases, like PostgreSQL (PostGIS), Oracle, SQL Server. I consider myself a flexible, working, pro-active person willing to get things done as efficient as possible. I'm either able to work alone or in a small team through Agile environment. Always willing to learn new habilities and share my knowledge.
