HydroSentry: Decentralized, offline-first Green GIS early warning system for the Lake Chad Basin. Engineered with TinyML, LoRaWAN, and React. # 🏥 OpenMed Lite (The Sahel Resilience Stack) > **Offline-first clinical record engine utilizing CRDTs, optimized for intermittent connectivity in extreme environments.** **🔴 Access the Live Clinical Engine Demo Here** *(Note for Reviewers: The live deployment utilizes simulated offline states to securely demonstrate the "Human-in-the-Loop" conflict resolution dashboard without exposing actual clinical data).* OpenMed Lite is the clinical health module of **The Sahel Resilience Stack**. It is an open-source, offline-first Electronic Medical Record (EMR) engine designed specifically for rural Primary Healthcare Centers (PHCs) and NGO mobile health workers operating in regions with severe telecommunication instability. ## 📖 The Manifesto: From Enterprise to the Edge As detailed in our REDCap v16.0.6 deployment case study, the University of Maiduguri Teaching Hospital (UMTH) served as the foundational stress-test for this architecture. By engineering a local-first server environment, we secured 99.9% uptime for their molecular lab during regional network blackouts. However, the heavy hardware required for enterprise hospital deployments cannot be sustained in off-grid rural clinics or by mobile NGO workers. OpenMed Lite is the evolution of the UMTH stress-test. It distills that enterprise-grade cryptographic security and offline resilience into a lightweight, CRDT-powered engine designed specifically for the last-mile. ## 🌍 Core System Capabilities * **Deterministic CRDT Synchronization:** Utilizes `RxDB` and `Yjs` (Conflict-Free Replicated Data Types) to allow rural clinics to read, write, and update patient data entirely offline. A mobile health worker can collect data on a tablet in the field all day, and the state will asynchronously sync with the master PostgreSQL database only when they return to a zone with broadband. * **"Human-in-the-Loop" Conflict Resolution:** Standard CRDTs resolve conflicts by blindly trusting the "Last-Write-Wins" timestamp.
