PROFESSIONAL EXPERIENCE:

Confidential, El Segundo, CA

Senior iOS Developer

Responsibilities:

• Participated in bug fixes in various parts of the application

• Implemented new classes in swift language and used the swift code in Objective C classes as well.
• Changed the code related to fetching the channels data, saving them into the new channel manager class.
• Understood and got familiarized with the huge code base and quickly accustomed with the implementation patterns followed by the team.
• Organized the data and updated the UI based on the new set of classes from the library.
• Sorted and filtered channels based on the new model objects.
• Added new methods and replaced the existing ones in the Application Data handler class to fetch the channels data.
• Implemented the UI design and service calls for registration of devices in the settings screen.
• Showed list of devices, register/unregister current device, rename device etc.,
• Created singleton Device Manager class for maintaining the device related information and the status of the devices.
• Exposed methods in this class for easy access of the devices data.
• Implemented private properties for checking if the device is enabled or not song the class extensions. Only this class can read and write such properties.
• Implemented common Alert View class to show the error messages from various service calls.
• Implemented call backs using blocks.
• Solved issues related to displaying HD Channels, filtering adult channels etc., depending on the data from server.
• Issues related to parental control settings, channel updates, UI without using storyboards, GCD.

• Clean reuse of Models, collection view cells, table view cells, view classes etc.,
• Implemented all the static screens at once.
