You lost me at Comic Sans. There is no way I can hide my loathing for that font -- all of the clients who had silly ideas about taking over the world from their little Mom'n'Pop operation during DotCom 1.0 insisted on it because it was "classy". I just can't take it seriously.
With most of the panels, it looks like the nav and content areas are two pieces of a larger whole. The arrangement has too big a gap for my taste, the contrast between the panels and the background is too low in my opinion, and I think the box-shadow is overdone, but the alignment makes the border-radius make sense. When the content panel expands (as it does for me with both "About" and "Softwares"), the shape of the panels doesn't make sense anymore -- they don't fit together to make a whole. The text may be reflowing differently for me than it does for you; maybe you're not seeing the panel expansion.
Oh -- "software" is a collective noun; it doesn't take an "s" at the end, ever.
I hope you take the harshness as a good sign. The site is much better than "meh", but it could be great with a few very minor changes. It's when I see signs of goodness that don't quite get carried through that I get really annoyed -- I can tolerate the truly bad, but the almost-right-but-not-quite puts me on edge.
