Kudos for including the information on Sippeo and slavery in general on the profile.
Most comments that spring to mind are just stylistic differences, which are not really a "right or wrong" thing, so any observation I had wouldn't be all that valuable to you.
One thing to correct though, raw html markup is displayed in the sources. A list of some sort? I couldn't quite figure out what it's supposed to be, otherwise I would have suggested a fix.
Overall good job
