Northwind Health required a patient mobile application to display customized daily care schedules, register clinical questionnaire answers, and support chat channels with practitioners. The primary obstacle was building a reliable offline sync process that protected patient medical data locally and encrypted all clinical logs using HIPAA-approved protocols on mobile devices.
We designed a mobile design system in Figma, focusing on high visibility and accessible text sizes. For the application code, we chose React Native, structuring local databases using SQLCipher for complete device disk encryption. We created a secure batch-synchronization queue that pools patient survey logs locally and sends them to Azure API gateways in chunks using transport-level TLS security once cellular connection is confirmed.
We design clean system flows that separate concern layers. Check out how data moves securely through this operational framework.
We implemented SQLCipher on Android KeyStore and iOS Keychain to encrypt device databases using keys generated dynamically per device.
We wrote CRDT sync models that merge changes made by patients on devices with scheduling updates pushed by doctors on the web portal.
We stay accountable for database performance and business outcomes.
“The only software vendor that proactively challenged our design and database assumptions. That rigorous architectural pushback is exactly why the finished product works.”
We supply monthly app updates, test suite evaluations, and security updates matching operating system patches.
