You should change your theme really its not fit for your niche and look for the better contents for your site
you need to change the header text info, you say your site is for technology, but you have included other stuffs that doesn't suite your website.
wow, the theme is very bad. im sorry but it is TERRIBLE. i sat here laughing for a few seconds thinking "who even made this theme??" .... alright, there are plenty of free themes at wordpress.org you can get that will fix this problem fast. the content isn't great so i would look into more quality content. the context of your design, content AND header don't match your niche - which is technology. hope this helps!
