I specialize in motivating teens & adults through their classes with 30' skype sessions. Reach me if you study: Now, I'm by no means knowledgeable enough to answer specific questions you may have on these fields. I can not offer tutoring. But I'm genuinely intrigued in and excited about the fields above, so I'll be very much interested in your field of expertise, your challenges, your progress, your ideas & goals & dreams on how to utilize that knowledge. I've worked as a freelance tutor on maths & physics and motivational coach. I currently self-study Data Science in coursera. These sessions will motivate both parts. That's why I'm happy to have a first skype session to everyone interested, no strings attached. If you enjoy it, we can have another one in the same week (for free as well) and then you can decide if you'd like to do that regularly or if that 'shot' of motivation has been enough.
