Numpy

Contributed to NumPy, principally to its documentation.

Why documentation

NumPy is a dependency of most of the scientific Python ecosystem, which means its documentation is load-bearing infrastructure in its own right. A concept explained badly there is re-explained badly in a thousand tutorials downstream, and the cost lands on everyone learning the field rather than on the library.

Documentation contributions are also the least glamorous and most durable way to help a project of that size: the code is written by people with deep context, and the docs have to work for people who have none.

What I contributed

Improvements to clarity and accessibility — making complex concepts more understandable for the data science and scientific computing communities that depend on them.
