A strong foundation in mobile architecture and design patterns (MVC, MVVM, VIPER, etc.).
Experience architecting modular, testable, and performant iOS codebases from the ground up.
Solid understanding of data handling, background threading, caching strategies, and persistence (e.g., Core Data, SQLite).
Experience with instrumentation and tooling for performance analysis, crash reporting, and continuous monitoring.
Proven ability to ship quickly without sacrificing stability, polish, or scalability.
Clear communication skills and comfort working closely with designers and cross-functional teams.
A Bachelor’s degree in Computer Science or equivalent practical experience.
