PROFESSIONAL EXPERIENCE

Confidential, San Francisco, CA

Sr. iOS Developer

Responsibilities:

• Redesigned, refactored and implemented 2 new versions of an existing Objective C API that wrapped (Using the facade design pattern) around two major AR Frameworks: Confidential and Confidential
• Decoupled the API by structuring and simplifying our interface to Confidential following the Facade design pattern.
• Followed the initial design around Blocks for callbacks, which was already using delegates and protocols.
• Reduced the flow complexity since blocks were harder to track at runtime.
• Implemented a CocoaPod repository for the wrapper to be included in other projects using CocoaPods dependency management.
• Refactored an existing internal app to use the wrapper API and explore NantWorks.
• Used Heroku as backend to change the overlay elements before they are rendered on top of the camera feed.
• Used CMS for creating and managing the content available to the AR API.
• Followed an Agile Methodology approach in weekly pod meetings, with a team of two developers, a UX designer and a project manager, to discuss progress and technical issues.
• Used CocoaPods to include our internally developed API.
• Worked closely with Confidential for new API functionality for our exploration of their API for new use cases, code reviews, and troubleshooting.
• Overcame challenges, such as, the implementing functionality of an only privately available API with no available information but only direct contact.
• Implemented an AR module for Target Wish List app currently on the Play Store (Android)
• Implemented Confidential Framework on Android.
• Used AREL (built on top of JavaScript) language for content creation and management.
• Implemented UI changes for Tablet and Phone using values.xml and Density Independent Strategies like providing drawables for every density group.
• Agile approach with a daily call with delivery managers and developers in a distributed team between SF, MLPS and ATL.
• Successfully completed the project within the tight timeline of 10 weeks for the whole project including requirements, development and QA fixes, with a geographically distributed team across the US.
• Used JIRA for QA bug fixing tracking and features missing management.
• Fixed crashes reported via HockeyApp, which allowed us to receive a stacktrace of every crash the app has run into by any end user.
• Conducted an Android Wear exploration by implementing a Shopping List app for Android Wear (Android)
• Gathered user stories by brainstorming with the team and separated them into releases.
• Implemented syncing between phone and watch using Android Wear APIs like DataApi, MessageApi and NodeApi.
• Input comes from the voice commands via Google Speech Recognition Activity, is cached on the watch and synced to the phone for sending it to Wit.ai and get back the response with the different important pieces of information.
• Implemented Voice Commands using Google Speech Recognition Activity.
• Uploaded the identified string to Wit.ai for online Natural Language Processing API to recognize the intent, the names and quantities of the products.
• Utilized the AND keyword to make it possible to mention more than one item in the same voice command.
• Implemented offline persistent storage that syncs automatically with the cloud using Parse.com.
• Led feedback sessions with members of the internal and external teams.

Confidential, Barrington, IL

Sr. iOS Developer

Responsibilities:

• Designed and implemented the application using AVFoundation from the UI to the application logic.
• Used the AVAssets to have access to the user’s library and allow the user to choose an input video file from the gallery
• Used AVFoundation framework to show the video timeline as a series of still images captured from the video file at different timestamps.
• The user is allowed to control brightness and contrast through logic using NSNumber and UIKit.
• Implemented logic to export the final video to the user’s library using AVAssetExportSession.
• Used AVFoundation to combine the video segments selected by the user into an AVMutableComposition that can then be saved.
• The user is allowed to add slides with text as part of the video and control the duration, color of the background and size and color of the text.
• Fixed bugs through personal testing using XCTest
