Professional Summary
I am a highly qualified manager with a background in mechanical engineering and a master's degree in Liquid
Propulsion Systems. Throughout my career, I have developed strong organizational, analytical and problem-
solving skills, technical intuition and strategic thinking. With over 20 years of experience in the field, I always
demand the best results from my colleagues and myself, finding new potential solutions to problems by
looking beyond current practices. I have extensive experience in managing testing and production facilities,
technical teams, and negotiating at various levels.
Relocation is acceptable. Ready for long-term business trips, as required.
