Prof. DSc. PhD. Hadžihafizović Dževad (DEng) is an independent researcher of mechanical engineering at the Faculty of Mechanical Engineering, Sarajevo, University of Sarajevo Department of Mechanical Production Engineering. Mentoring Welding, steel structures, piping, corrosion & Oil & Gas Professionals | Consultant & Content Creator | Worked for Major Oil & Gas Companies.
He successfully presented his graduation thesis on February 11, 2002 in the area of Metal Processing by Plastic Deformation and received a MSc mechanical engineering degree.
He got a job at GD aerospace and defense company as a constructor until 2013. https://www.researchgate.net/publication/374152080_Constriction_of_rockets_tank_ammunition_and_other_ballistic_missiles 
At the beginning of 2013, he went to field work with KRESTA Industries - Austria, KMM department:
Welding and construction. I work as a construction supervisor in Uruguay on a pulp mill construction project. There he gets practical knowledge in the field of tank braking and gets a welding certificate, i.e. International Welding Engineer by Böler Welding Group.

At the beginning of 2014, he went to field work at Akakus Oil Operations in Libya, in the position of Engineer on the construction site, at the oil field NC 115. There he gained practical knowledge in the field of the oil industry.
After successfully completed projects abroad, he returns to Sarajevo and begins his career as an independent researcher in the field of welding and materials.
At the beginning of 2018, he published a paper in the field of Fracture mechanics - XFEM -Extended Finite Element Method, Sarajevo. 2018.
Which is the first book on the basis of which he received the DSc mechanical engineering diploma.
