for the new React Native application.

Architect and build a resilient synchronization engine to handle bidirectional data flow between the device and our FHIR backend, implementing a hybrid push-pull model.

Define and implement an intelligent

merge-based conflict resolution

strategy to prevent data loss in a high-stakes, disconnected environment.

Manage local data storage, including large binary files (e.g., medical images, documents) on the device's file system, ensuring efficient access and a dual storage approach.

React Native Development & Leadership :

Lead the design, development, and maintenance of a high-quality, scalable, and secure React Native application from scratch.

Define and implement scalable component architecture and state management strategy.

Conduct thorough code reviews to ensure high standards of code quality, security, and performance.

Act as a technical mentor for junior engineers, fostering a culture of continuous learning and excellence.

Collaborate closely with our native Android and iOS teams to ensure seamless functionality and knowledge transfer.

API Integration & Health Tech Domain :

Integrate a

GraphQL API

alongside

RESTful APIs

to deliver efficient and dynamic data handling from our FHIR backend.

Implement FHIR-compliant solutions for seamless interoperability with healthcare systems.

Architect and implement real-time, event-driven features using Pub / Sub patterns and WebSocket principles.

Security & Compliance :

Enforce a

security-first, privacy-by-design mindset

throughout the development lifecycle.

Implement robust on-device security measures, including

hardware-backed key management and AES-256 encryption , to protect sensitive Protected Health Information (PHI) and ensure compliance with regulations like

HIPAA, GDPR, and DPDP .

Innovation & Continuous Improvement :

Leverage

AI-assisted coding tools

to accelerate development while maintaining a strong sense of critical thinking and code ownership.

Stay up-to-date with the latest trends in React Native, mobile architecture, and health tech to ensure our application remains at the cutting edge.

Proactively address technical debt and enhance the scalability and maintainability of the codebase.
