A/B tested on who? I see hundreds of resumes throughout the year and your resume is one that I would likely pass over because, frankly, it looks like something a young student slapped together real quick in MS Word compared to the average resume I see.
When it comes to design, I immediately notice that the font size for your name is much too big (especially compared to the email address). Then there is the page header (Qualifications) which takes up around 10% of the page on its own. Under the 'Related History' section, the name of the projects take up way too much space while the font-size of your job title and duration of stay are hard to read. Why do you need that empty white block next to the name of the projects? All this wasted space not only makes the resume's layout ineffective but also makes it look very unprofessional.
Content-wise, the core of your resume should be what you have under 'Related History'. I want to be able to get a good idea, quickly, of what you did in your past positions. Based on that information I can get a good idea of pretty much everything you have under 'Qualifications'. I would cut all of 'Qualifications' out and summarize everything in there into 3 - 4 bullet points/short sentences. Also, why did you bold seemingly random words like 'CMS' and 'infrastructure'?
Honestly, I would just stick to something like https://www.careercup.com/resume. Remember, the key point of your resume is to quickly communicate your past experience and highlight relevant information.
