    I love code and creativity. I'm a software developer with a wide range of experience. I've spent countless hours writing software for Windows, using various technologies ranging from simple (Access, VBA, VB.net) to complex (C++, MFC, MS SQL). I've created from scratch several successful iPhone apps, and updated many others. I have years of experience working with CSS, PHP, HTML and Wordpress. I'm also a designer. Currently, I'm working in the marketing industry. Logo design, website design (and implementation!), branding, and print design. For years, I've been into photography and sound design - it's something I really enjoy. Lately, I've been getting into video work and cinematography. Despite my wide range of experience, code is my passion. I love making stuff work and solving problems - and I love doing it in an elegant, user-friendly way. You'll find that I'm competent in most areas that involve IT, but especially developing software for the Apple mobile ecosystem. I live in the United States (East Coast) and always have - English is my first language, and we will have no trouble communicating. I also work full-time for a real company, doing marketing work. I'm very good with communication, team work, and customer service.
