Responsibilities

• Implement the remaining application workflows for iOS and Android based on already-defined UX designs.
• Refine and polish the user experience across both platforms.
• Integrate the mobile app with the proprietary backend - order processing, driver tracking, admin capabilities.
• Prepare the app for production release - build configuration, store submissions, release pipeline.
• Use AI-assisted development tools as part of the daily workflow, while reviewing and validating generated code for quality and security.
• Refine and estimate new tasks according to client requirements.
• Work closely with the client and team to translate requirements into clean, functional code.
• Proactively identify bottlenecks and improve overall app stability and performance.
• Address technical challenges and bugs.

Requirements

• 4+ years of hands-on mobile development, with strong commercial experience in Flutter as the primary stack.
• Proven track record of releasing and maintaining apps on both the App Store and Google Play, including store submission and review processes.
• Proven experience consuming RESTful APIs; experience with real-time communication (WebSockets / streams), token-based authentication (JWT / OAuth), and role-based access control.
• Practical experience with Google Maps / Mapbox SDKs, background location tracking, route rendering, and ETA logic.
• Working knowledge of FCM push notifications, Crashlytics, Analytics; familiarity with deep linking.
• Hands-on daily use of tools such as AI-assisted development tools; ability to prompt effectively, integrate generated code into an existing codebase, and critically review its output.
• CI/CD experience with mobile pipelines (Codemagic, Fastlane, GitHub Actions) and app distribution (TestFlight, Firebase App Distribution).
• Ability to implement designs accurately from Figma and suggest improvements where workflows can be simplified.
• Strong problem-solving skills with the ability to communicate technical decisions clearly to both technical and non-technical stakeholders.
