Mason Choi
Hi! My name is Mason Choi. I am a rising senior pursuing a dual degree in computer science and mathematics (with a concentration in statistics+data science) at the University of Massachusetts Amherst. I work as the lead software engineer at a finance AI company and cofounded an AI shopping startup. My interests range from machine learning and AI safety to scalable cloud infrastructure and data processing. I am a competitive fencer at the national level, and am an avid stock+option investor, 3d printer, climber, and fisherman 🎣.
These are some of the projects I have developed over the years, starting from the most recent to the oldest. I have been creating projects with code since 2018.

March 2021 - Present
Anchor was a website providing multiple regression model predictions on over 2,500 stock symbols. Its Tensorflow model was run daily in an AWS Elastic Cloud Compute (EC2) instance, assets stored in AWS S3, and website built with Django.
Simple fencing analysis tool that spliced fencing video footage for fencing frames only with a CNN, reducing average watch time by over 40%.
Both my AI composer and AI singer fashioned Long Short-Term Memory (LSTM) models to generate their own, original musical pieces. This required webscraping, data cleaning, and, of course, machine learning (ML).
