IT Professional in Data Warehouse and reporting area with perfect sense for data. It means data structures, quality, data products, data transformations and vizualization. I am used to work in large enterprise architecture with hundreds of various data sources. I have perfect analytical skills and ability to see consequences and to evaluate a lot of steps in advance. I am also flexible, agile and I use prototyping to get first results very soon. I like learning and I am excited about new challenges. I am familiar with the whole process of development in DWH and BI area from analysis, dealing with requestors, estimations through development to testing and production support. I can also create stunning, self explaining and visually attractive dashboards. My sense for visual design hopefully prove awards from Czech Press Photo.
