How to reduce left margin in this Sharelatex (Professional CV) template?

Question

I have been trying to reduce the space in the left and right margins of this template? The initial image is

So, I added

\usepackage[a4paper,left=-20mm,top=26mm,right=-26mm,bottom=-20mm]{geometry}

in the preamble. However, the result is not as I expected (the horizontal lines go to the far right end, while the left margin space stays intact). I would like the left margin space to nullify as well. How can I go about this?

The code:

\documentclass[a4paper,10pt]{article}
