Weeks 1 - 3

In the first 3 weeks, I grasped the basics of machine learning, including model operations, training, and algorithms. I also crafted 3 browser-based projects using JavaScript to transition smoothly from my background in JavaScript development to the field of Data Science.

Project 1- A color-detecting machine learning model powered by ML5 JS
Project 2- A model used to predict the distance of golf shots from my own training data
Project 3- An LSTM model created to predict the future of the S&P 500 Index

Weeks 4 - 6

In the next 3 weeks I brushed up on my Python and learned more about Data Science and Machine Learning. I created 6 projects in Python during this time, teaching myself important concepts for these fields. I learned about data cleaning, data preparation, data modelling, 3D models, pipelines, data imputing, scaling, feature selection, feature engineering, and many more.

Project 4- An analysis and linear regression model to help waiters make more money from tips

Project 5- An analysis and model to help students determine their chances of admittance to university

Project 6- A KNN Classifier to explore multi-label classification of enzyme substrates

Project 7- A Gradient-Boosting Classification model used to predict potentially dangerous asteroids

Project 8- My second data science competition submission, a feature selection and engineering exercise used to predict kidney stones before they form

Project 9- An advanced analysis and modeling exercise to help understand how stars are classified

Weeks 7 - 8

In the next 2 weeks, I worked on 2 major projects using all of the knowledge I had gained over the past 6 weeks.

Project 10- A data analysis project to determine how much the Subreddit r/wallstreetbets affects the stock market.
Project 11- A Wordle variation made to help people learn the region of origin of over 10,000 surnames. This was a cooperative project alongside CMU '24 Chris Choi.

Weeks 9 - 10

My final project: a way for people to find economic, social, political and demographic data for their Congressional District. Submitted as an entry for the Congressional App Challenge

Extracurriculars

Golf

I started playing golf when I was 5 years old. My father used to bring me along with him to the golf course and I instantly developed a love for the game. I have played in over 200 junior golf tournaments over a period of 9 years and have been on my school's varsity golf team for 4 years.

Cubing

I began competitive Rubik's Cube Solving in 2015, when my parents bought me a cube for Christmas. I have been to 13 total competitions and have completed 381 official solves. At one point, I was ranked top 300 in the world and top 100 in the USA for my 2 main events. My WCAID is 2018VIRA02.

Robotics

I have been a programmer on my school's robotics team for all 4 years of my high school career. In 2021 and 2022, I was the lead programmer on my school's freshman and JV robotics teams. In 2023, I was the backup programmer on my school's varsity FRC team and this year, I will be the lead programmer on the team.

Music

I have been playing piano for 11 years, and I have been playing violin for 4. I have been a member of my school's string orchestra for all 4 years of high school and have played in numerous piano recitals. My school's string orchestra plays at masses, has concerts and other events where the school needs us to play music.

Media

I joined the media club as a freshman and served as a technical assistant for two years before being promoted to lead technical director. I gained experience in areas of media such as filming, video editing, graphic design, social media management and livestreaming. I personally manage the golf team's Instagram account, @boscogolf, feel free to follow!
