“David and I worked on the same team for a short time at the beginning of my continuous 2 year internship at Splunk. David helped me learn many things from git branching to coding standards for several programming languages. David is the master of code reviews, he consistently gave well-rounded and justified feedback to myself and others. Whether it was an unnoticeable tab indent or a deprecated function, David caught it all. His code reviews made everyone a better programmer and he will be missed.”

TypedDict for mypy (Python's reference typechecking tool)
See projectmypy is the official reference typechecker for Python. It is analogous to TypeScript (for JavaScript), Hack (for PHP), and Dialyzer (for Erlang).
TypedDict is an important kind of type that classifies dictionaries/maps with a known set of keys. These are extremely common in JavaScript, JSON, and web development in general. TypedDict is analogous to TypeScript's "interface" type and Hack's "shape" type.
I wrote the initial implementation for TypedDict in mypy. Other contributors…mypy is the official reference typechecker for Python. It is analogous to TypeScript (for JavaScript), Hack (for PHP), and Dialyzer (for Erlang).

I wrote the initial implementation for TypedDict in mypy. Other contributors have extended this implementation since then. TypedDict became an official part of the Python language in Python 3.8 as part of PEP 589. -
HandBrake's SSA subtitle support

See projectHandBrake is a popular program for converting movie files from one format to another.
I extended HandBrake to support subtitles from file inputs (in addition to DVDs) and to support the SSA/ASS subtitle format, which is a rich subtitle format commonly used in foreign TV shows and movies.
