It's strange that this person didn't also describe the lessons they'd learned about Content Marketing, but I guess it doesn't work if you point that out.

This person may have accidentally reinvented content marketing but they aren’t implementing a known good strategy. They are a web developer, a coder, available for hire. They say they’re a consultant, which is nice but they don’t understand the difference between a consultant and a contractor. A consultant is way more expensive. If this person has a marketing position or a niche I don’t know what it is. I’m completely convinced they’re a good web developer but they don’t have a market position more differentiated than “I build websites”.
FWIW my own pipeline of consulting clients relies solely on introductions and blogging ("content marketing" but much less formal). I continue to encourage new freelancers/consultants to write and share their knowledge more often.
