I am a software engineer with a background in signal processing and wireless networking & communications. In a nutshell, I enjoy using math and software to solve interesting problems.

I am currently working on building tooling and infrastructure to make machine learning easier to use for the average software engineer, and along the way engender best practices for ML.
