Senior iOS Mobile Engineer

Capital One, McLean, VA March 2020 to Present

https://apps.apple.com/us/app/capital-one-mobile/id407558537

Capital One wanted to reduce false claims of fraud. A iOS technology team was assembled to overhaul the Capital One app so that the bank notifies the user whenever there is a sketchy transaction, and only then can the user report fraud or dispute other transactions. The team created new plugins and removed old ones. I coordinated with other teams to document APIs and request new features for our team, and also discuss the app flow with the design teams.

- Worked with a team of 4 Developers, 1 Tech Lead, 1 Team Leader for both iOS and

- Android teams, 1 Project Owner, and 1 Scrum Master.

- Worked in an Agile environment with daily scrums, 2-week sprints, and 2-week PIs of 3

- sprints.

- Utilized Jira to manage sprints under an Agile methodology.

- Reviewed design documents and created views using Storyboard, XIB, and

- programmatically.

- Used a proprietary architecture called Toolbox v2 to create plugin with a reactive

- store architecture.

- Ensured type safety and application interoperability between Objective-C and Swift Languages to avoid runtime errors

- Migrated legacy code from Objective-C to Swift.

- Migrated architecture from MVP to MVVM.

- Used Interface Builder to build UI/UX via Storyboards and SwiftUI.

- Documented APIs from other teams for our team to work with.

- Used deeplinks to create a separate flow for different use cases within the plugins.

- Organized with Android sister team to ensure both teams are aligned with the design documents.

- Used Zoom for meetings and Slack for team chats.

- Manually tested voiceover in both Spanish and English to ensure that accessibility elements were being read to the user with proper pronunciation.

- Created user testing accounts for both Android and iOS teams, and conditioned them for fraudulent transactions using TDM.

- Assisted other teams with testing account conditioning for our plugins.

- Created several screens using our generic view controllers for Fraud Detection Plugin.

- Removed deprecated code from the previous versions of plugins.

- Created UI test robots to verify elements on screen of plugins were displaying.

- Coordinated with accessibility and design teams to fix accessibility issues in the app.

- Created generic view controllers for screens that would use the same elements, but display different data.

- Updated documentation from deprecated plugins and APIs.

- Oversaw regression testing to ensure all our tests were still good after updates.

- Recorded UI tests to verify the flow of the deeplinks using XCUITest with a Robot Pattern.

- Verified the texts, icons and other screen elements with unit tests using XCTAssert.

- Manually tested other teammates’ PRs on physical device.

- Created unit tests for each of our added elements, including analytics tags.

- Moved elements that could be shared between our plugins to a generic location and adapted them for use by both plugins (fraud detection and transaction disputes).

- Source controlled with Git using SourceTree and GitHub.

- Reviewed/approved code from team's pull requests in GitHub.

- Uploaded strings for translations in Lokalize and verified their Spanish translations were correct.
