I have worked at LzLabs as a software developer since 2016, where I am responsible for COBOL and PL/I compiler runtime development and compiler integration, and legacy C370 runtime implementation. Before LzLabs, I worked for IBM for close to 20 years, working on the lowest level guts of DB2 LUW. I spend too much of my free time, when I can find it, enjoying recreational mathematics, physics and engineering studies. At http://peeterjoot.com/ you can find my book on geometric algebra applications to electromagnetism, free pdfs of class notes for many of the physics and engineering courses that I have taken, and my musings about math, physics, programming, and other random topics that have caught my interest.
