Photo-processing iOS platform

Overview

A photo-processing iOS platform built in Swift for a confidential client. I developed and supported it as a senior iOS developer and managed the iOS side of the team.

Responsibilities

• Developed the iOS app and supported the existing project.
• Managed the iOS team members and kept the work in line with project requirements and technical standards.
• Kept the app updated on the App Store.
• Worked with Product, Design, backend, and QA.

Selected engineering work

• Designed a modular iOS SDK for the platform: a disk cache backed by NSCoding, a UI styling system, pagination, thread-safe utilities, and photo transfer.
• Refactored Redux state management by memoizing selectors, moving data from global to local state, and adding a thread-safe access layer. Measured list re-renders dropped by about 30% in Instruments traces.
• Designed REST API specs with Swagger.
• Automated delivery with Fastlane and Jenkins, using parallel jobs and CocoaPods caching.
• Led the creation and App Store launch of multiple iOS applications.
