– Core Languages: Strong proficiency in JavaScript (ES6+) or TypeScript.
– State Management: Experience with state management libraries such as Redux, MobX, or Context API.
– Native Integration: Familiarity with integrating third-party libraries, native modules, and interacting with device hardware APIs.
– Workflow Tools: Hands-on experience with Git and issue-tracking tools (preferably JIRA).
– Language: Advanced English proficiency (reading and writing).

– Native Development: Experience with native mobile languages (Swift, Objective-C, Java, or Kotlin).
– API Knowledge: Solid understanding of RESTful architecture and JSON data handling.
– App Stores: Experience with the submission and release process for the Apple App Store and Google Play Store.
