If you look at the commit history and contributors, it's mostly him.
By that metric, he did half the work. But it still means he completely disregards the other half.
vs
46 commits, +478, -94 LOC
I think it's safe to say it was mostly him.
Out of the 273k LOC added, all but 20k, that is 253k are just from the boilerplate auto-generated copy/paste initialization code: https://github.com/JDKaim/HuskySwap/commit/e9f0df0d5a221b3c7...
Sure he probably did most of the coding, but it's still weird to talk all about I and not mention the other 5 in a single word when they _did_ contribute. Maybe they did testing or other things that are not reflected in LOC, e.g. presentations etc.
Update: I see, LightNap is the work of Ed Kaim, surname checks out. https://github.com/SharpLogic/LightNap
