// ARCHITECTURAL OVERVIEW
An app deployed for health administrators and parents to track children's nutritional and developmental growth metrics.
// ENGINEERING SPECIFICATIONS & SYSTEM DESIGN
01 / System Architecture & Data Topology
Built as an offline-first mobile healthcare tracker using Flutter and SQLite. Designed for frontline health workers in rural environments with intermittent or zero cellular connectivity.
02 / Technical Challenges & Performance Solutions
Ensuring absolute zero data loss during synchronization handshakes. Built an automated background queuing pipeline that detects internet recovery and writes structured milestones directly into Google Sheets and Google Drive APIs.
03 / Security Model & Data Resilience
Conforms to World Health Organization (WHO) child growth reference standards. Includes input validation to prevent anomalous entries and exports digitally timestamped records for administrative compliance.
// CORE CAPABILITIES & SYSTEM FEATURES
01.
Track nutrition milestones, vaccination histories, and medical checklists.
02.
Google API integrations syncing data directly to target Google Sheets, Drive, and Calendars.
// TECHNOLOGY COMPONENT STACK
