I have over 5 years of professional 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, C++, Python, Java, functional programming languages such as OCaml, Haskell, F#, Prolog, Scheme/Lisp/Racket, etc. I can help with CS topics such as algorithms and data structures, Computer Graphics, Cryptography, Compilers, Programming Paradigms, CS theory (Finite Automata, Regular Expressions, Context Free Grammars, Turing Machines, NP completeness, etc.). I'm also happy to help with other math, such as Calculus, Discrete math, Statistics, Number Theory. If you want help with something other than what I've listed above I can usually debug anything, but I might be learning the material along with you.
