    United States - Last active: 2 days ago - Tests: 1 - Portfolio: 5

    I am a web designer & front-end web developer skilled in HTML, CSS3 & Adobe Creative Suite as well as template platforms including Squarespace, Shopify & Wordpress. My extensive experience & background in graphic design allow me to bridge the gap between design & development to create the most beautiful, & highly functional, websites. I draw inspiration from my background in 3D design disciplines (including interior, fashion, and fine arts) and instill this awareness of physical space and interactivity into all of my digital and print projects. Working freelance for a diverse clientele, I have gained experience throughout all stages of the design process, including conceptual design, information architecture, branding, marketing, animation, art direction, and development. I have blended these experiences as both a designer and developer into an enhanced understanding of interactive design - from the inside out. In addition to decaf digital, I am the owner & designer of decaf plush, a vintage inspired children's clothing company featuring my own retro animal & fruit illustrations, crafted in felt & appliquéd. I am currently the lead creative director (REMOTE) for a technology company based in Los Angeles, CA, as well as the owner of decaf digital, an independent design consultancy. After studying architecture for 2 years, I earned my BA in Environmental Design from Art Center College of Design in 2000.
