I love solving problems. Give me the puzzle pieces and let me work to figure out how to put them together in the most effective and efficient way. With my background in education, I've been solving problems on large and small scales for almost a decade. 

Now, as I've developed my data analysis skills with SQL and Python, I'm excited by the process of exploring data and revealing the story it has to tell. To me, this work is about accessibility: taking complicated concepts, columns of numbers, and unrefined information and translating it into language and visuals that can be understood and acted upon by the relevant parties. I'm known for going above and beyond in my places of work and for finding solutions even when faced with the most challenging constraints. Let's work together to solve the problems faced in your company or organization!
