Josh Gilbert

Josh Gilbert

Yet Another Rockstar Developer

United States

I live and breathe information technology. I could type my own name before I could write it. I began writing software at seven years of age under my father's tutelage. I began working as an independent contractor in the field in my early teens and have remained entrenched in it since that time. With nearly two decades of professional and hobbyist experience in desktop, mobile, and web application development across a variety of platforms (iOS, Linux, OS X, and Windows, and more) as well as the personal management and discipline skills necessary to survive as an independent contractor for the majority of my life, I can bring just about any project to life. While my development philosophy is holistic, I have been known to obsess over what I consider critical details. To summarize: even while a chain is no stronger than its weakest link, the burden isn't always equally distributed. I would also offer a paraphrased thought from Antoine de Saint-Exupery: Perfection is achieved not when there is nothing else to add, but when there is nothing led to take away. As I had developed a wide range of skills outside of formal academics, I got a late start in college. Now I'm just another student trying to make ends meet as I labor toward a lifelong dream of establishing my own information technology firm. I am as committed to technology as any one person may get. In closing ... I love technology and I love working with technology ... it is both a hobby and a career. I am one of the few people who are lucky enough to have a strong passionate enjoyment of what they do, and I'm eager to put that passion to work for my clients and their projects.
