Ensuring the highest level of data security and privacy for Protected Health Information (PHI) while maintaining a user-friendly and performant system. This involves adhering to strict compliance standards, securing authentication, and preventing unauthorized data access.

Implemented NextAuth.js v4 with a MongoDB adapter for robust authentication and secure session management, complemented by bcryptjs for password hashing. Role-based access control (RBAC) is enforced server-side for all sensitive operations, and input validation with Zod schemas prevents malicious data injection. Continuous security audits and dependency updates are planned to maintain compliance and mitigate vulnerabilities.

Providing a reliable user experience even in environments with intermittent or no internet connectivity, while ensuring data consistency and seamless synchronization once online.

Integrated Progressive Web App (PWA) features and implemented a custom OfflineSync mechanism using offline-storage and offlineFetch utilities. This allows users to continue operations offline, with changes queued and automatically synchronized with the MongoDB backend when connectivity is restored, enhancing availability and data integrity.

Generating complex medical charts from uploaded images and converting them into standardized, shareable PDF reports, often requiring server-side processing for reliability and performance.

Utilized a combination of html2canvas for DOM-to-canvas conversion and jsPDF along with pdf-lib for client-side and server-side PDF generation. The /api/charts/pdf endpoint specifically handles server-side PDF creation from images, ensuring consistent and high-quality report outputs regardless of client environment, and integrating with Cloudinary for image management.
