Okay, let’s tackle this. So Aldemar has 18 years of experience as an electrical engineer and manager. Skills like Microsoft Office, Excel, Word, PowerPoint are in demand for professionals in his field. Location is Colombia, which is a developing country with a lower cost of living. Considering his experience and skills, I would estimate his hourly rate to be around $75, which is a reasonable rate for a mid-level electrical engineer in Colombia. This rate is lower than what I would expect in a developed country like the US, but it's still a good starting point.
