A results-driven iOS Engineer with 7 years of experience developing and launching highly successful applications, achieving over 350K downloads. Expert in multiple iOS frameworks such as SwiftUI, UIKit, Core Data, and Concurrency, with a proven ability to optimize for performance and memory management. Proficient in architecting applications using MVC and MVVM patterns, and adept at implementing UI/UX principles to create intuitive and engaging mobile experiences.

• Refactored a UIKit banking application to SwiftUI as part of a four-engineer team, modernizing the user interface resulting in a 15% improvement in initial load times.
• Utilized Instruments to analyze and optimize encrypted data handling, resolving a memory leak and reducing memory consumption by 35% during large data operations.
• Engineered core functionalities using SwiftOTP for a password manager application, including token storage and generation of time-based one-time passwords (TOTP), improving user security and account protection.
• Leveraged CryptoSwift to implement on-device AES-256 encryption for secure storage and management of sensitive user credentials, including usernames, passwords, and TOTP secrets.
• Developed fluid and engaging user interfaces by leveraging Core Animation to create custom animations and transitions within a messaging application, enhancing user experience and application interactivity.
• Architected and maintained comprehensive unit and UI tests using XCTest and XCUITest, ensuring code reliability, functionality, and a 30% reduction in crash reports measured by Sentry.

• Physics Simulations in iOS using Swift and SceneKit

  • Built sphere simulation demonstrating mass-dependent behavior and wind force effects.
  • Designed particle system for fluid behavior simulation using SceneKit's physics engine.
  • Implemented physics-based interactions between 200+ particles and solid container.
  • Tuned physical properties (restitution, friction, damping) to achieve realistic fluid dynamics.

• Box3D, a 3D extension of Box2D in C++ (In Progress)

  • Implementing rigid body dynamics.
  • Implementing an iterative constraint solver.
  • Implementing collision detection: dynamic AABB tree (broad-phase) and SAT/GJK (narrow-phase).
