ABOUT

This site is intended to be a gateway to examples of my skills for working with python and large, complex datasets. This is primarily through problems I’ve solved using LeetCode and StrataScratch; although I’ve also developed a codebase for processing stock market data and a news tracker. To avoid a wall of text, LeetCode problem links are now on a separate page: LeetCode solutions. As the purpose of these solutions is to exercise problem solving I don’t use A.I. to solve the leetcode and stratascratch problems. My codebase is mostly my code combined with some code prompted.

If you’re unfamiliar with what LeetCode and StrataScratch are the following paragraph is an explanation: LeetCode is a platform that provides coding problems in several languages at varying difficulties and I’ve used it to solve general python problems and problems with the python library pandas. StrataScratch is more ideal for solving problems with datasets; however, I found it after I started working with LeetCode and therefore have solved fewer problems on the platform.
