Not a big fan of the word "expert", but anyways. I have been studying various math related subjects during the last 10 years. Those include computer science in Armenia; actuarial mathematics, statistics, economics in the USA; and machine learning, artificial intelligence, computer vision in Sweden.
I would be happy to share my knowledge that I gained in the past including: 1. Data driven predictions in business, marketing, biology, etc. 2. Data visualization 3. Where and how to apply to universities in the USA, Sweden, and other places 4. Statistical consulting 5. Who are actuaries and how to be an actuary in the USA.
