Experienced Software Engineer Seeking New Opportunities

After I got my PhD in math, I've worked as a university professor (postdoc) for a few years, but now I want to switch from academia to software engineering or related fields. I have 20+ years of coding experience (as part of my job and as a hobby), particularly systems level programming in Linux. As a math researcher, I'm used to solving hard problems without established solutions, and I enjoy learning new things every day. I'm open for any opportunity where my skills can be useful. Examples I have in mind are working on compilers, high-performance computing, or machine learning (both on the math/statistics side and the algorithms/optimization side), but I'm also happy to hear about anything else!
