    iOS Developer

    United States - Last active: 03/05/2014 - Tests: 4 - Portfolio: 1

    I'm an Apple guy. My focus is iOS applications - it's what I love, and by far my strongest skill set. I got my start in mobile by creating several indie apps for Palm OS. By the time iOS 3.0 was released, I had already started learning Objective C. In 2014, I was in Moscone Center cheering as Swift was unveiled to the world. I'm fairly familiar with it at this point, but am taking a conservative approach to implementation. The language is maturing fast and I expect to be writing Swift code for production soon. I'm active in my local developer community, and always looking to learn new things (Go, React Native, and so on). I currently work out of two coworking facilities: one in my hometown, Lancaster, and the other in Old City Philadelphia. I'm a huge fan of coworking and the communities that it creates and fosters. Lest you think I'm a mobile-only guy, I have extensive background in general software development. In the past, I've worked with .NET + Microsoft SQL/T-SQL, web front end technologies (HTML5/CSS3/JQuery/PHP), C/C++, and even assembly way back in the day. In the interest of becoming the best mobile developer possible, I've chosen to focus exclusively on iOS development for the time being. That said, I'm deeply fascinated by language fundamentals and 'good' programing practices, and I continue to invest heavily in learning new tech. I won't be iOS forever.

    Anne Wallace

    Freelance Writer

    United States - Last active: 2 months ago - Tests: 3 - Portfolio: 3

    I'm an attorney-turned business academic, who can turn some pretty arcane stuff into lively readable copy. I practiced law in the employee benefits field before turning to teaching at a community college. I teach a wide variety of courses including English, Business Law and American government. My first love is writing, though. My experience makes it possible for me to wade into some technical areas others might find daunting and drag out the treasure. It's not good writing, no matter how scholarly, if no one wants to read it. I've published in print in national journals like Compensation and Benefits Management and Benefits Quarterly. My online portfolio includes blogs, white papers and research pieces on legal and educational topics, but I'm always up for a new challenge.
