In middle and high school I participated in many math competitions. At the pre-olympiad level I recommend Art of Problem Solving's Counting and Probability series. At the olympiad level I recommend *Problems from the Book*.

Some teaching experiences:

- During summers 2015, 2017, 2018, and 2021 I was an instructor at the Math Olympiad Program.
- In 2016 I cofounded Contest Math Tutoring.
- In 2018 I coached Brazil's IMO team for one week in Sao Paulo.
- In summer 2021 I coached Ghana's IMO team via the MISE Foundation.

Olympiad problems I contributed USA team selection tests, in increasing difficulty order:
