Typedframes brings static type checking to pandas and polars DataFrames, catching column name errors at lint time via Python type annotations. Its novel use of descriptors for refactor-safe access and support for both pandas and polars makes it an interesting approach to a common runtime bug problem. While still a proof of concept, it fills a known gap in the Python data stack.

Target audience: data engineers, data scientists, backend devs
