As a Software Engineer, I architect and build iOS applications. I assist in the planning of features, scheduling, and backend server API flows. I also have some experience adding features to the Android apps, as well as working on backend servers as well. Although I am confident in my skills as an Objective-C developer, I was an early adopter of Swift, starting a brand new project with it just 2 months after its release. To ensure the quality of my apps, I use CircleCI to build and test my apps using Quick and Nimble. They go very well together to make readable test output that make it easy to see when something goes wrong.
