Flutter Developer | Building Scalable Android & iOS Apps | Dart • Firebase • REST APIs • FastAPI • AWS | Clean UI & Performance

I'm a Flutter Developer with hands-on experience building and delivering production-ready mobile applications for Android and iOS using Flutter and Dart. My experience covers the complete mobile development lifecycle—from designing responsive and user-friendly interfaces to integrating backend services, third-party APIs, payments, real-time communication, testing, performance optimization, and publishing applications to the Google Play Store and Apple App Store. I have worked on applications across different domains, including healthcare, real estate, utility apps, mobile gaming, and audio applications. Some of my key projects include an Ayurvedic doctor consultation platform, a real estate application, a period tracker, a 2D mobile game, and a bedtime music application. My technical experience includes Flutter, Dart, Firebase, Hive, FastAPI, REST APIs, Git, Zego Cloud, Google Mobile Ads, and AWS services such as Cognito, DynamoDB, Lambda, CloudWatch, and Config. I enjoy turning ideas into clean, scalable, and practical mobile applications with a strong focus on performance, maintainable code, and great user experiences. I'm continuously improving my skills and exploring better ways to build modern, reliable cross-platform applications.
