Hello! I am a software engineer in Boston, MA. I graduated from Northeastern University in '22 with a Bachelor's of Science in computer science. I ran track & field and fell in love with computer science. When I am not coding 🧑‍💻, I'm playing video games 🎮, watching F1 🏎️, cooking 🧑‍🍳, skiing 🎿, or playing with my dog 🐶.
