Mathematician with Software Engineering and Data Science Skills

I'm a mathematician with 4 years of research and teaching experience post-PhD. I'm looking to leave academia for a job in software engineering, data science, or anything where my math and computer skills can be useful. As a mathematician, I am used to tackling hard problems without established solutions. I learn quickly, and through years of teaching and presenting my research I am also good at communicating complex ideas. I've been programming for most of my life, and often use computer experiments in my mathematical research. Some projects are on my website. I have also worked in the industry a bit before my PhD (on simulation software in C++ and C#). I especially enjoy relatively low-level programming, performance optimization, Linux kernel development, embedded devices, and similar things. More recently, I started reading about and experimenting with machine learning (my math background is useful there).
