Data Warehouse Architect

I am a Data Warehouse (DWH) expert with solid knowledge and proven experience. I have 12+ years within the Business Intelligence (BI) field and I've worked on a different type of DWH projects: from small ones to medium sized and large scale solutions. My core competences are DWH and ETL design and implementation, but I have no fear to create complex charts and dashboards. Over the years I've gained experience of various DWH/ETL/BI tools and technologies like: Teradata, Oracle, MS SQL Server, Pentaho BI, Microsoft BI (SSIS, SSAS, SSRS), and many others. I'm looking for challenging DWH, ETL or BI projects.
