    Scientific/Exploratory Lisp Programmer

    Poland - Last active: 18 hours ago - Tests: 7

    I'm a physics student with broad interests in mathematics, computer science, cognitive science and space exploration. I'm looking for challenging projects incorporating mathematical concepts, with a strong emphasis on exploration and prototyping. Delivering production-ready applications is less fun to me than thinking of something original and challenging. I prefer to be forced to explore an uncharted territory than to follow "industry best practice". My language of choice is the Lisp family (especially SBCL and Racket). I'm also strongly dragged towards functional languages (mostly Haskell and Ocaml). I'm ready to learn new stuff if it means thrill, excitement and novelty.
