Mobile App Development

Built static UI and dynamic components for large-scale automotive mobile applications using React Native with custom camera integrations and real-time features.

Push Notifications & APIs

Designed and implemented custom push notification systems and RESTful APIs for seamless client-server communication and real-time user engagement.

State Management

Architected middleware layer using Redux-Thunk, Redux-Saga, and Redux-Logger with Universal React Redux for complex state management across the application.

App Store Deployment

Successfully deployed production applications to Google Play Store and Apple App Store, managing release cycles, versioning, and compliance requirements.

Microservices Optimization

Optimized backend microservices using Node.js and ESO as interfaces to Cassandra NoSQL database for high-performance data operations.

System Design & Documentation

Created UML-compliant high-level designs including data flow diagrams, class diagrams, sequence diagrams, and comprehensive documentation for development teams.
