    Graphic Artist

    Canada - Last active: 1 day ago - Tests: 2 - Portfolio: 3

    Born and raised in the province of British Columbia, Canada. I have been a freelance graphic artist for approximately 11 years. My primary focus has been in logo design and brand/identity development. I have always been intrigued by the artistic world but my logical brain is also very strong and drives me to play with numbers to no end. These two personality traits are why I have always felt at home in the world of design. Whether it's colours and tint percentages, to shapes and letterforms in ratios and fractions and calculating the negative space in between. The constant equations between form and function. That's the process.
