    View some of my work below or on Dribbble at http://bit.ly/WBagQx A true Interaction Designer and consultant with professional experience working with teams varying in size from the light and nimble lean start-up to SCRUM driven teams working on multiple products at once, moving with agility towards a similar vision. Through years of varying work, with a multitude of differing clients and partners, my work focuses predominantly on envisioning new mobile, web, and desktop applications and services. My passions lie in creating consistent design frameworks that span a multitude of devices with solutions that: target usability above all, does not sacrifice aesthetics or perceived quality, while offering unique and engaging experiences. My process includes (but is not limited to): - defining a project scope and roadmap (with stakeholders) - determining and valuing specific user types - defining: tasks/goals/motivations, work-flows, calls-to-action(s), style guides, messaging, content, branding, etc. etc. - prototyping/ideation through static and/or dynamic wireframes using tools like: InVision, Axure RP, Omnigraffle, and Balsamiq. These wireframes can vary from the very basic to the most complex; mimicking interactions, animations, and visual effects. - to deliver a framework and library of components, patterns and interactions that enable an individual, with minimal effort and energy, to meet a desired need. The solution includes a design with limited distractions, layouts that focus on a clear hierarchy and displays only the information necessary to achieve targeted interactions, and provides a distilled and powerful solution. Let me help you create that "next big thing", your next product release, your big break, a new startup, or simply something you believe can help out a lot of people. _________________________________________________________________ *Returning to oDesk upon successful completion of several long term contracts. *Serious offers and inquiries only, please. tags: user experience, graphic design, user interface, ixd, ios, android  less
