    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.

Backbone.js Developers & Programmers
 
The JavaScript object-oriented scripting language is one of the most widely used and portable languages available to developers and programmers on the market. JavaScript is a high-level, dynamic computer language often considered one of the backbones of the World Wide Web. With its implementation and use near ubiquitously across all online systems and workstations, it has become an essential tool that businesses in the modern online workspace often find themselves interacting with. Backbone.js is a JavaScript library with only one dependency and is optimized to help JavaScript programmers and developers design efficient and simply coded webpages. Working with a Backbone programmer and developer allows you to implement this specialized JavaScripting functionality.


Hiring a freelance Backbone.js programmer or developer gives your project or business flexible access to not only a professional and experienced JavaScript programmer, but also an expert with talent and skill working with Backbone.js. JavaScript programmers are capable of working on and developing code for a variety of general applications, whereas programmers and developers who are familiar with Backbone.js are experts in creating single webpages and synchronizing them with other services, webpages, and online resources. Freelance programmers and developers who have the ability to manipulate both JavaScript and Backbone are the ideal solution to any project looking to create effective and simple single webpages and dynamic applications. Find an array of qualified Backbone.js developers and programmers on Upwork, and browse their particular specialties to hire one who best fits your project plans.
