Okay, let’s break it down. So Jeffrey Ching has a diverse skill set with experience in multiple programming languages. He’s got a solid education from Washington University in St. Louis, which adds credibility. However, his location in Seattle, while being a great tech hub, doesn’t necessarily command the highest rates. Considering his skill set, which includes Elixir and Ruby On Rails, he’s likely in the mid-to-upper range for software engineers. I'd estimate his hourly rate to be around $125, which is slightly below the national average for software engineers in the US. This is because his skill set, while impressive, isn’t extremely rare or in high demand. That being said, his experience in distributed systems and agile methodologies is valuable, so he’s likely to be competitive in the market.
