500px for iPad and iPhone
I was hired in 2011 as the iOS developer at 500px. I architected and shipped the iPad application. I helped design new features, plan the product roadmap, and respond to customer support inquiries, all while continuing to ship an amazing product.
Eventually, the team grew, and I stepped up to fulfil the team's lead position. From there, I played a crucial role in the design and development of the iPhone application, which shipped late 2012.
Users find the 500px iOS application hard to put down. On average, more than 40 minutes is spent in the app, which is far, far above normal.
I'm very proud of what I accomplished at 500px. At the time, the iOS app was my greatest professional accomplishment.
