My first task as Lead Developer was to work with the original developer on translating, rewriting and refactoring the app's Objective-C codebase into Swift v2.1. I worked closely with the founder and CEO of Spare on the features of the app, marketing ideas and aided in managing daily operations. Besides app development my responsibilities included interviewing and hiring a full-time backend developer and a part-time web developer, as well as overseeing a corporate partnership.• Managed and guided the engineering and DevOps teams to sustain a robust 95% uptime for all key product services.• Oversaw the development and successful deployment of four significant software releases,enhancing product functionality and client satisfaction.• Employed strategic leadership to ensure smooth operations and maintenance of critical systems, contributing to the continuous availability of products.

After completing an intensive program at the New York Code and Design Academy, I co-developed a social sharing application: CrowdKat - https://itunes.apple.com/us/app/crowdkat/id988450587?mt=8. I learned an incredible amount about iOS development and became very familiar with Core Location, RESTful API design, push notifications and remote databases (with Parse), third-party SDKs and Core Image. CrowdKat was developed with Swift v1.2 and in November of 2015 we upgraded the codebase to Swift v2.0.
