Senior Python Problem Solver

I am a problem solver, and my main tools are Python and Postgres, though my programming approach is informed by Lisp (many years of Emacs contributions), Prolog (the best kind of mind-bending) and OCaml (which I wish I was writing instead of Python). I would like to be solving real-world problems: energy, logistics, communications, governance, trash removal. It's amazing what you can find out if you talk to people about their problems, and its amazing what you can solve with a concoction of fairly straightforward data science, ML, calculus, signal processing, and Rube Goldberg machines.
