I was working in the start-up (by that moment) which is an aggregator of banking and financial products and services located in Russia with focus on entrepreneurs and corporate clients. The project was relatively new, and I started to work for it, and it developed from one's idea to a start-up company.I was an Executive Assistant of the CEO on the unpaid internship with a variety of functions/tasks during that interesting time. I wished to learn something new on such an ambiguous project which related to the spheres of my interest - IT and Finances. As a total, I learned very useful experience and knowledge which helped me to understand the business, its business model and some practically useful skills. My main tasks was: - research of proposed commercial offers by banks and financial organisations on offered products. - contacting & negotiating with them regarding the placement of products on aggregator.- preparing and modifying of internal documentation.- Assisted in the creation of graphic materials for the use of the marketing department.- primary data analytics based on financial data with reports.- Preparation of recommendations regarding the product development.
