As a designer who is so proud of being a Vietnamese, I tend to transport the Vietnamese essence to my every design elements.
At first glance there is the full name of me - Nguyen Phu Hai, which was shortened into Ng. Phu Hai since ‘Nguyen’ is the well-known first name of Vietnamese, accompanying with the diacritics that are exclusive for Vietnamese ( ~ | ‘ | ? ). The diacritics were symbolized in a grid system that was further used in other visual elements.
The logo is finalized by wrapping the full name and diacritics inside a square box, which is only used in white background and colored in black.
