Okay, let’s tackle this. So Roman has 10+ years of experience in finance, which is a solid foundation. He has worked in two prominent companies in Ukraine, which suggests he has industry connections. Skills like financial modeling, valuation, and due diligence are in demand. Location is Ukraine, which might impact his rate. Considering his experience and skills, I estimate his rate to be around $125 per hour, which is slightly below average for finance professionals in Ukraine. This is because his experience is not excessively long, and he might not have worked in top-tier investment banks. However, his skills and industry connections suggest he can command a decent rate.
