who is a product designer?

A product designer is a specialist who is responsible for identifying product problems, proposing solutions for improving it, and implementing changes based on the product's business strategy.

Until now, there is no unambiguous, well-established definition of the profession of a product designer, so there are stereotypes that a product designer is someone who draws products. In fact, this is a generalist - he has broad skills and an understanding of the basics of a number of highly specialized professions: UX designer, graphic designer, researcher, analyst, prototyper, marketer, business strategist. Product designers are in demand and make good money. here you can see for example vacancies and how such companies work in general: https://fireart.studio/services/motion-design/
A product designer is a person who must combine three basic roles. The first is responsibility for the quality of user experience. It must regularly receive feedback from users, conduct research on the current user footprint within the current digital product, and continuously improve it. And also think about the improvements that are in demand, conduct research to study user demand.

The second big area of ​​influence is the orientation in the technological world in order to come up with optimal solutions from the point of view of technical development of problems. It's like an architect - on the one hand, there must be an aesthetic role, on the other hand, he must understand technology.

The third is expertise related to the digital product business. He needs to understand the monetization model, strategy, understand the main metrics of product viability. Each of his decisions should be dictated by an understanding of these metrics and be maximally focused on increasing them.
