Refactored my current portfolio grid :) Decided to remove margins for a cleaner look and removed slideshow functionality because things became too slow and it really doesn't need it.

(Questions below.) At this point I probably just whine about job search in IT w/o much commitment. It's because I don't learn stuff from interviews and have no willingness to prepare for primitive questions from HR's book. You know, stuff like: "What was your experience on previous jobs and why you quited them?" and "What are your advantages and cons?"
Even though I see them a bit discriminatory. I barely find words and make them audible alrite, and so rush to the stack questions. I answer 50% of them in average, 20% ideally. As a result, I get no conclusive offer. Fair... probably not. Doesn't matter.

All of a sudden, idea chimed in to make a personal website with all of the frequent questions answered in advance. At last, I've got some time to make the decent replacement of the CV into a landing page that communicates my professional and emotional ability to headhunters.

TL;DR: I wanna make my personal website portfolio and I need your word about the following.
1) Can I make up for the absence of my own live projects with OSS commitments or other smooth talk?
2) Is there a merit in answering the common interview questions right off the bat in written form?
3) So, I already prepared 4 conclusive theses with thoughtput choice of words, that I wanna place as a grid in first scrolling section. I call it "Principles", but perhaps there is a synonym to this one or it's good as it is?
4) I don't want to represent myself as a blunt set of "features". How do I transite into explaining the usage of my stack in these circumstances? Less text better, right?
