I’m a Flutter Developer focused on delivering production-grade, cross-platform mobile applications with a strong emphasis on performance, reliability, and clean architecture. I’ve worked on healthcare-focused and real-time products, designing features that feel smooth on Android and iOS while staying aligned with production standards.

At FamCare, I develop and maintain cross-platform mobile features for a healthcare platform, collaborating with product and backend teams to integrate REST APIs and real-time experiences using WebSockets and Firebase. I apply Bloc/Cubit state management alongside clean architecture principles to keep codebases scalable and maintainable as product complexity grows. In parallel, I’ve engineered modular Flutter codebases at Centre for Future Studies and Research, using strict architectural state decoupling to boost client responsiveness by 30%.

My technical edge is building robust offline-first and secure client workflows. I designed an offline-first storage architecture with SQLite to securely cache transaction data, reducing local state synchronization latency to sub-100ms, and I implemented JWT-based token refresh loops with secure payload encryption and global interceptors for strong REST API error boundary handling.

I also bring an experimental, outcome-driven mindset from hackathons—where I won 1st place for architecting an optimized transit research mobile client and earned 1st place for uncovering production-level vulnerabilities and memory management leaks. In projects, I’ve built real-time stateful chat experiences with WebSockets, Firebase, Bloc/Cubit, and streaming UI components driven by LLM token updates, while minimizing layout jank and thread blocking during high-volume operations.
