About bernadetteengleman

Hello, I am Bernadette from New York City. I moved here from Chicago in 2013. I am originally from the Philippines. I started studying web programming in 2015. I love it because I like making fun websites and web apps. The projects that I built so far are posted below. I like to cook and I love to travel. I also like to volunteer and I am a team leader with the non-profit organization, NYCares.
