I have over 5 years of professional CS tutoring experience (and 1000+ positive reviews on chegg tutors before they closed). I have worked with students of all levels of experience, from high school to grad school. I'm an expert on C++ and python. I know quite a bit about functional programming languages such as OCaml, Haskell, F#, Prolog, Scheme/Lisp/Racket, etc.). I'm also good with discrete math, algorithms and data structures, and CS theory (Finite Automata, Regular Expressions, Context Free Grammars, Turing Machines, NP completeness, etc.). I've taken upper level classes on topics such as AI, programming languages, compilers, computer graphics, virtual reality and web programming (HTML, CSS, javascript).
