Sonja Josipović

Mechanical Engineer

I am Sonja Josipović, a graduate of the Faculty of Mechanical Engineering in Belgrade, specializing in thermal engineering. I am particularly inspired by projects focused on environmental protection, energy efficiency, and gasification of buildings. The combination of my education and practical experience has enabled me to work effectively in teams, communicate clearly, and successfully lead projects.

In my current role, I have developed a wide range of skills, including creating conceptual designs and projects, preparing feasibility studies and techno-economic analyses, as well as calculating and sizing HVAC equipment. My experience in reviewing systems and equipment on-site has further enhanced my ability to implement engineering solutions in practice.
