Well, the user has, technically, been involved in development of many high-profile projects, that is hard to disprove. Yes, that involvement consisted solely in bumping "2015" to "2016" in READMEs, but I probably wouldn't include such a detail in my CV (if I were to write one (or even write one based on such activity ;)))
I can't imagine any other reason for such massive number of merge requests - but I admit my imagination might be limited. Perhaps the account holder also reads HN and could enlighten us?
