    Graphic Designer

    Philippines - Last active: 1 day ago - Tests: 11 - Portfolio: 9

    I am an independent graphic design professional doing logo and brand identity design including web/app/ui and print design. I started full-time freelance graphic designer in 2005 doing print design works for local small advertising businesses, small entrepreneurs in my province. My work ranges from posters to large print design, packaging/label design and logo design. Few years before 2005, I have also worked as part-time graphic designer for a politician designing campaign posters, banners, computer wallpapers, logo and ID design to it's political party. I am a self-taught designer. I respond well to a challenge and enjoy the rewards of hard work and dedication. I am an undergraduate computer science student - during my college years, I have gained knowledge and skills on HTML and CSS aside from programming languages I used to love. I follow my passion for art, design and love for my work when I begun working online full-time from 2007 doing logo, graphics and web design. I have honed my skills on logo and brand identity over the years. I also do and love painting, which I hope to continue again. Until now, I continue learning design and in the previous years I have worked further on UI design- web and mobile. I have front-end web design/development experience as well as designing mobile app UI for android and IOS devices. https://www.behance.net/bobsagun | http://bobsagun.com

Most of UI is in storyboard. I can use any VCS, but git is my favourite one. My experience is not limited by C / Objective-C / Objective-C++ / Swift.
