VISHNU P

I am a full-stack mobile app developer with experience in both frontend and backend development. I handle the complete app lifecycle, including authentication (OTP-based), payments, push notifications, and maps. I work extensively with Flutter for frontend and Node.js for backend services. I’ve integrated Firebase (Authentication, Firestore, Realtime Database, FCM), MongoDB, and Azure Cosmos DB. I use Postman for API testing and have deployed applications on Firebase, Azure, and Vercel. With strong knowledge of cloud services and real-time data handling, I build scalable, user-focused applications optimized for performance, security, and seamless cross-platform experiences.
