Okay, let’s break it down. Constantin has 11+ years of experience as an IT System Administrator, which is a valuable skillset. However, his degree is in Electrical and Electronics Engineering, which might not be directly applicable to the IT industry. Location is the Greater Toronto Area, Canada, which is a competitive market. Considering the lack of direct experience in software development or related fields, I'll estimate his rate to be on the lower side of the spectrum. A more experienced IT professional with similar skills might charge $100-$150 per hour. However, given his unique blend of technical and non-technical skills, I'll place his rate at $75 per hour, which is slightly below the average for an IT System Administrator in this region.
