Hi there,
I am java developer with 7+ years of experience in web and desktop app and game development.
I have strong expertise in oop, data structures, statistics, multi threading, networking, genetic algorithm implementation and more.
I am not aware of Cutting stock or Bin packing problem, but pretty sure would be easy and willing to learn, understand and implement.
Have a look at my profile for my portfolio and similar projects I've completed with reviews.
Message me, we can discuss further details over chat.
