I am a developer at Quansight Labs. I am a core maintainer of Numpy and PyPy. and through that work have contributed to many other projects. In addition to contributing to python performance, I love teaching and helping new people learn how to use python and how to make it fast.

Ask me about Open Source, getting involved in NumPy development, or when to use PyPy in the real world, or consider sponsoring me here
