Building a Quant/Investing/Data Science resume as a high school senior

I’m a high school student going into his senior year who wants to start achieving things such that I can build up a quant/investing/data science resume. I hope that this would help in both my plans to transfer to a top tier college and to help find business/coding internships. I’m aware of competitions such as Google Code-In, Wharton Investing competition, USACO, and challenges on Quantopian and Kaggle. I’m just wondering if there are any other competitions/challenges I should be aware of that I should try to place in and what other activities I could do other than app development, paper trading, and simply practicing/learning. Thanks.
