    Video and audio production.

    United States - Last active: 2 days ago - Tests: 3 - Portfolio: 19

    Hi, I'm Jon Simpson - thank you for visiting my profile. I am a multi-media artist and producer that specializes in creating across a broad range of visual, audio and conceptual contexts. Since earliest memory I have been very diversely creative and I am now utilizing a wide array of professional design tools that channel that ever-expanding experience within the digital realm. As a "generalist" artist I seek to master and stay current with each software tool, not merely to maintain cutting edge capability, but also to maximize and expand the creative options available to myself and my clients. My primary video/2D animation software is Adobe After Effects (5 years), which is now integrated with and partnering with Maxon's Cinema 4D, my 3D software. I am currently ranked in the top 20 out of more than 6,000 on the oDesk After Effects skills test, and in the top 2 percentile on the basic English skills test. For audio, I have been producing in Adobe Audition for over 10 years, everything from music composition (5 instruments across diverse genres, including full symphonic orchestration), to managing multi-language voice overs, world-class singers, genuine foley sound effects, podcasts, instructional courses, children's stories and more: http://www.reverbnation.com/AvalonStudios I also have more than 7 years of experience in Photoshop and Flash and over 3 years with Illustrator, Camtasia and Cinema 4D. Educationally, I have a Bachelor's degree in philosophy from the University of North Florida with subsequently highly developed critical writing skills, able to help you with scripts, articles, copy, editing and much more. I am in the -5 GMT time zone but as I am willing to accommodate any time zone and schedule, my availability is very flexible and generous. Contract-wise, I enjoy doing various kinds of projects but I am also interested in developing long-term relationships in more specific contexts with individuals and organizations I resonate with. Please enjoy examples of my work in my oDesk portfolio, read client reviews, and feel free to contact me, even if you just have questions and want to explore possibilities. I look forward to the opportunity of creating with you! Jon
