    "Connie delivers excellent work. She is very professional, checks-in to make sure she is delivering exactly what the project entails. She delivers high quality work in a timely and efficient manner. Highly recommend!" The way you analyze, and present data can transform the success of your project. Your data is foundational in making decisions, but it’s only useful if you're able to use it and present it to your clients in a way that they understand. Using informed approaches, I can work with you to convey to others the value of your data. An important aspect of working with data is to tell a story. My work can help you tell your “story”. If you have an existing dataset that requires: -data mining, -statistical analysis, -qualitative analysis, -dashboard production, -infographic and reporting design.
