    Business Intelligence and Software Development Expert

    Germany - Last active: 22 days ago - Tests: 1

    Lars has more than 9 years of experience helping companies across a broad array of industries to deploy planning capabilities in form of business intelligence solutions to significantly improve business performance. With a lot of passion for technology and vision for modern, pioneered innovations Lars shaped from a software developer via IT Management positions up to a specialist for business intelligence solutions. Over the last several years, Lars has focused on bridging business towards technology in order to deliver best-practice approaches for business intelligence solutions. In his former position with Digital Tempus he helped global companies (TOP 50 Fortune) to shape needs for sales and operations planning and transform those into an insight-driven planning solution based on Microsoft’s Business Intelligence and .NET stack. The fruitful combination of deep knowledge of both, software development and business intelligence, alongside the capability to understand and transform business needs, makes Lars a widely positioned and respected business intelligence expert. His great and deep expertise in the entire Microsoft database and BI stack, especially database services, integration services as well as analysis & reporting services allows Lars to accomplish basically every complex task. -- I reside in Germany but my time is very flexible so even when you are located elsewhere I can definitely make sure to make myself available whenever you need me. I work for almost 10 years in the area of information technology. To be more precise I owned my own software development company, focusing on windows based client developing under C#, WPF, SQL Server, WCF and all the good stuff that comes with it. While my team (and I) have been focusing on this side I got myself involved for the recent 4~5 years in the area of Business Intelligence. I am on an expert level in terms of data warehousing and business intelligence solutions under Microsoft Technology. SQL Server, Analysis Services, OLAP, MDX, DAX, PowerView, PowerPivot and even Power BI and Sharepoint is something that I work with on a daily basis. I am also very engaged in software development. That is what I learned back than and that is what lets me build a "face" on top of all that data analytics. My recent project was about an enterprise business planning suite developed in C#, WPF, WCF. It has just recently been rolled out to around 150 users all over the globe.
