Okay, let’s tackle this. So Ruben has been working as a programmer for 31 years, which is a long time. Considering his experience, I would expect his rate to be lower than that of a software engineer with similar experience in the US or other developed countries. However, his experience is still valuable, especially in Peru where the market might be different. Let’s look at some benchmarks. According to Glassdoor, the average hourly rate for a software developer in Lima, Peru is around $25-$35 per hour. Considering Ruben’s experience, I would estimate his rate to be around $75 per hour, which is on the higher end of the average rate.
