When data comes to my world

I achieved the Bachelor’s in Computer Science from Southern Polytechnic State University in 2012 and the Master’s in Engineering Management from University of Southern California in 2014. Like most of the new graduates, I did not know what my career would look like. However, I know I love data and how powerful the data is.

I am passionate about data. Everyone talks about data now, but do you know what data means to the business and how data can ultimately help the company make money? As a senior data analyst, my job is to make data accessible, present data visually, communicate data insights, and make recommendations to help business users make actionable decisions. Instead of providing pages of numbers, I use data to tell stories.

This website is the place to not only share my ideas of data analysis, visualization, insights and storytelling, but also share how I grow personally and professionally. I’d love to spread my positive energy to the world. Let’s start…
