Okay, let’s tackle this. So Adnan has 6 years of experience in construction and project management, which is a good starting point. However, his role as a Senior Mechanical Engineer at CEG International is more specialized. Location is Sarajevo, which is not a major hub for engineering professionals. Considering his experience and education, I'd estimate his hourly rate to be around $75, which is on the lower side due to location. This rate is also influenced by the fact that he doesn't have any specific certifications or advanced degrees. Some mechanical engineers with similar experience in major cities might charge $100-$150 per hour. So, this rate is a bit conservative, but considering the location and lack of additional qualifications, it's a reasonable estimate.
