Anticipate data correctness and performance issues and suggest improvements, especially for timezone, currency, channel filters, and on-device analytics.
Contribute to the codebase and verify acceptance criteria before sending tickets to QA.

Work with backend, data, and analytics engineers on Parquet schemas, Firebase Storage sync flows, and SQL or DuckDB query requirements.
Maintain and enhance the app by fixing bugs and monitoring performance with Instruments.
Implement and improve offline-first sync, including Parquet download, local caching, and DuckDB import.
Provide architectural feedback on how to scale mobile applications as data volume and feature scope grow.
Write concise documentation and own App Store release processes, including code signing, provisioning, TestFlight, and App Store Connect submissions.

Experience implementing Sign in with Apple and Google Sign-In flows.
Comfortable working with SQL and embedded or local databases such as DuckDB, SQLite, Core Data, or Realm; DuckDB or Parquet exposure is a strong plus.
Experience with Combine or async-await-based reactive data flow.
Familiarity with Swift Package Manager for dependency management.
Proficiency with Xcode 16+, LLDB debugging, and Instruments performance profiling.
Experience building and testing large-scale, data-heavy iOS apps such as BI dashboards, analytics, or reporting apps is a strong bonus.
Exposure to offline-first sync patterns, file I/O, and local data caching.
React Native, Flutter, Swift Charts, or Fastlane, Xcode Cloud, or GitHub Actions CI/CD experience is a bonus.
