Senior Flutter Developer

We are seeking a highly experienced Senior Flutter Developer to architect, develop, and optimize a complex cross-platform astrology application with real-time communication features, deep API integrations, and scalable backend connectivity. The ideal candidate must have hands-on experience in building enterprise-grade Flutter apps, strong knowledge of mobile system internals, performance tuning, API architecture, and secure app deployment workflows.

Key Responsibilities

• Architect and develop a production-grade Flutter mobile application for both Android & iOS with high responsiveness, optimized rendering, and strong state-management patterns (Bloc / Riverpod / Provider).
• Build and integrate REST API modules communicating with a PHP/MySQL backend hosted on cloud servers—ensure secure, optimized, and scalable API consumption.
• Implement real-time communication using Agora SDK (audio/video calling, channel management, session handling, background mode, token refresh).
• Integrate Firebase Cloud Messaging (FCM) for notifications, topic subscriptions, advanced payload handling, and background execution.
• Work with Vedic Astrology API for horoscope generation—ensure accurate data binding, caching logic, fallback handling, and computation speed.
• Implement secure OTP verification flows using AiSensy, including async handling, retry logic, fallback methods, and number masking.
• Integrate Google Maps Geocoding & Google Places Autocomplete for location-based workflows, optimized API billing, geospatial accuracy, and smooth UI.
• Build payment workflows with the Razorpay Payment Gateway, ensure PCI-compliant data handling, error mapping, and transaction lifecycle tracking.
• Collaborate with backend and admin panel developers using PHP, MySQL, Bootstrap, JS, and ensure API specifications match app requirements.
• Maintain advanced error logging, crash analytics, performance monitoring, and implement best practices for memory optimization.
• Manage entire app deployment lifecycle on Play Store & App Store including signing, release pipelines, versioning, crash debugging, and rollout strategies.
• Conduct advanced testing: unit tests, widget tests, integration tests, performance audits, load simulation, and edge-case handling.
• Review and improve UI/UX fidelity, animations, transitions, and app fluidity according to modern mobile standards.
• Produce high-quality technical documentation, maintain code standards, and lead junior contributors when required.

Required Skills & Expertise

• 3+ years professional experience with Flutter & Dart.
• Strong understanding of native Android (Kotlin/Java) and iOS (Swift) bridging for advanced plugin or feature customization.
