Unique psychology and mathematics background enhances all aspects of work - from AI development and analytical problem-solving to understanding human behavior in sales, leadership, and strategy. Seeking senior roles that combine strategic leadership with hands-on implementation.

"I believe in leading from the front, actively participating in both technical and commercial activities while knowing the details of the company or project. An effective team is as small as possible, containing only skilled people on an as-needed basis. Team decision-making is driven by expertise, exchange of ideas, and shared vision, with minimal hierarchy. A successful outcome is the reward for work, toward which we strive together."
