Hi, I'm Mabel!

I’m a computer science student at Cornell who enjoys building things that people actually use. I’m currently an Android developer with Cornell AppDev and will be joining M&T Bank as an intern this summer. I like working on products that people use in their daily lives, especially ones that feel tangible! Outside of coding, I’m usually trying new coffee shops and restaurants, going on runs or hikes, or putting together fun outfits. I also really enjoy meeting new people, so feel free to reach out!
