    Specialized in human interface design, backend development and iOS app development. Human Interface Design ---- Keen on creating easy to use interface, have been practicing in this area for many years, was in charge of app design in quite a few projects. It's a habit for me to think about "user experiences" -- whether playing with various apps or using an ATM machine. Website Backend ---- From development to deployment, specialized in Django framework. Stacks include database, "Unix-like" sys admin and well-written Django helper libraries such as South, Tastypie, etc. Also have experiences on GAE, AWS, etc. iOS App Development ---- Not a fresh iOS programmer, started writing programs for the Mac platform when Mac OS X was merely 10.1 and Xcode was Project Builder. Workflow ---- For iOS app development, mockups will be built using tools like Balsamiq, to settle on an overall tone. And then, milestones will be set. Services like github is recommended, to make the code management and cooperation easy. Misc ---- - A Mac box is my major "workstation", testing devices include iPhone and iPad. - Projects list in "portfolio" are all my own stuff. For other projects, I would need client permissions of public listing. Please check my job history or ask.

    Multi-Media Journalist, Writer, and Artist

    United States - Last active: 14 days ago - Tests: 4 - Portfolio: 11

    I'm a professional multi-media journalist who can write, edit, research, produce, and design high-quality content on almost any topic and for any medium. From creating blog and social media posts to complete marketing communications plans, I have worked with clients including university programs, acupuncturists, chefs, commercial painters, e-commerce sites, news sites and forums, and more. I do not compromise my high ethical standards. Sorry, but I do not accept jobs that involve "ghostwriting" without credit, "spinning" and stealing others' copyrighted work, or other shady practices. What you get with me is a passionate, hard-working, detail-oriented, mass communications expert. What you do not get is someone who will rush the job or be a mindless "yes man" -- if I accept a job then I am committing to give you my best work effort, and that includes sometimes offering suggestions or advice -- getting you the final product you NEED, not just the one you think you want. I generally do not do Skype interviews or meetings for any projects paying less than $1,000. I am happy to answer any questions through ODesk or email, and I am happy to do a trial period for any ongoing positions. Sorry, but the reason I choose to do online freelancing is to make my own schedule and work in my pajamas; if you can't deal with that then best of luck finding someone who is a better fit for you.
