I am learning Python, R, and SQL
SQL is an excellent skill to invest in. Even though your current role doesn’t allow you to use it, there’s no substitute when pulling data from a relational db.
It sounds like you’re currently focused on data quality. Automatic data quality checks are common features of (good) data workflows so this could be spun as relevant experience if you end up seeking a role writing data transformation code.
Wow how are you liking the 3000k sft-40??
