With extensive experience in Mobile App Development, I have designed, developed, and deployed high-performance applications across iOS and Android using React Native, Flutter, Swift, and Kotlin. My expertise includes building scalable architectures, integrating RESTful & GraphQL APIs, and optimizing UX/UI for seamless user engagement. I have implemented real-time features (WebSockets, Firebase), secure authentication (OAuth, JWT, biometric login), and third-party integrations (payment gateways, analytics, push notifications). Leveraging cloud services (AWS, GCP, Firebase), microservices, and DevOps (CI/CD, Docker, Kubernetes), I ensure smooth deployment and scalability. My experience includes performance tuning, offline capabilities, accessibility optimization, and security best practices, delivering robust mobile solutions for diverse industries.
