I have recently finished an iOS Developer internship at a company called TextNow. During the duration of this internship I worked on a large-scale project with legacy code in Objective-C and Swift, operated in an Agile environment on an iOS team of 10 developers with 2-week sprints, collaborated with the monetization team to maximize ad revenue, and worked specifically on bug fixes, ads, messaging, contacts, UI tests.
I am also an iOS Engineer for an app called WYA: Where you at. I joined the team after launch and some colleagues and I work on this project part time. I work on new features and bug fixes and operate in an Agile environment.
