    I've spent the last few years developing quality iPhone and iPad apps in a wide range of genres, from physics-based platform games like Big Sticky to database applications like the pedigree app for the American Arabian Horse Association. I also have several years of experience with web programming and design, and my expertise with SQL, PHP, Javascript, Ajax, CSS, and related libraries often allows me to create more powerful applications both on iOS devices and on the web. The modern tech environment is an increasingly social one, and social applications require connectivity. That is what my particular combination of skills has to offer. I have also worked extensively on the graphical side of design, and am proficient both on paper and in Photoshop. I'm an experienced writer (essay, informative, tutorial, technical, fiction, SEO, and content), with over 700,000 words of content produced at the present time and several essays and short stories published both in print and on the web. I am seeking freelance work from creative and free-thinking clients with big ideas and innovative approaches to the 21st century.  less
