SQL

I use SQL on a daily basis to query and aggregate data that we hold at work; it's an invaluable tool for me as an analyst. The platform that I am familiar with from my professional life is Redshift or Microsoft SQL server but I also have some experience with SQLite and PostgreSQL. Below are some examples of personal projects that demonstrate part of my competency with SQL. These are a bit dated now, i've since extended my knowledge of SQL to include more advanced topics such as windows functions, stored procedures and so on.
