"The languages I have had the most exposure to are SQL, Java, R and Python. I am most comfortable using SQL since this is the language I have used most often in various school class projects. However, I enjoy expanding my programming knowledge base by learning new languages. I realize that sometimes one programming language may not be the best solution in every scenario."
