I am passionate about database design and visualisations in a way that it speaks for themselves. I have been helping companies create data representation, optimization and visualisation solutions by understanding business needs, not only how to make charts. I realize that data is often complicated, but it doesn't have to look that way if we design it properly from scratch. I combine my experience in data analysis, visualization, and design with the awesome capacities of Power BI to make data understandable and beautiful. My Data Stories are crafted to communicate information in the clearest, most efficient manner. I believe that the more effectively the data is presented, the more easily the information is consumed. Power BI has fantastic capabilities that allow information to be presented in an appealing, clean style, yet still contain all of its intrinsic depth and complexity. From engineering the data to the finished dashboard, I make the complex approachable. I am experienced, professional, and I have a passion for what I do. I am pleased to offer complimentary consultations online or by phone. I can also provide you with a sample visualization of your data for a nominal fee. I look forward to learning about your project and I appreciate this opportunity. I’m able to: Build Power BI report using DAX and Power Query Translate your business problem into compelling storytelling via dashboard Calculating all your metrics for your business Connecting all data sources (Database, Azure, AWS, Google Cloud, API, flat files etc) into Power BI and also build custom API connector Setting up a cloud platform for your BI reports in Azure & AWS (Refer to my other gigs!)
