Damibu Feeds CMS

The Challenge: We needed a sophisticated, multi-tenant content management system that could deliver culturally-adapted healthcare information to diverse communities. The system required complex content relationships where feeds could follow and customise content from other feeds while maintaining security and content integrity.

My Role: Full-stack development and architecture leadership. I was responsible for all aspects including frontend dashboard, backend API development, database design, security implementation, and the complete migration from MySQL to PostgreSQL Aurora.

Frontend Development: Built comprehensive React.js dashboard providing intuitive content management interface. Implemented real-time content editing with live preview capabilities and advanced user management with role-based permissions for multi-tenant security.

Backend Architecture: Designed complete RESTful API using Node.js and AWS Lambda serverless architecture. Built scalable microservices handling content management, user authentication, feed relationships, and content distribution. Implemented comprehensive security layer, API rate limiting, and SQL injection prevention.

Database Migration Leadership: Initially architected using MySQL, then led complete migration to PostgreSQL Aurora specifically to implement advanced vector search capabilities for improved content discoverability and relevance.

AI Integration: Integrated AI-powered translation APIs with custom validation workflows. Built translator interface within CMS enabling human validation and correction of AI-generated translations, ensuring quality while enabling multi-language content delivery.

Impact: Powers content delivery for thousands of users across diverse cultural communities. The platform's flexible architecture enables personalised healthcare information delivery in multiple languages while maintaining quality, security, and cultural sensitivity. Builds trust within diverse communities by delivering health information that honors cultural values and linguistic preferences, fostering better health outcomes through cultural competency.

CATCH (Common Approach to Children's Healthcare)

The Challenge: The NHS needed a comprehensive mobile application to provide parental guidance from pregnancy through 5 years. Critical requirements included complete offline functionality, intelligent age-based notifications, location services for NHS facilities, and integration with local healthcare providers.

Platform Migration Leadership: Originally architected using C++ with Cocos2dx engine for cross-platform development. I led a complete migration to React Native, improving development velocity and maintainability while preserving all existing functionality and ensuring zero disruption to users.

Offline-First Architecture: Implemented encrypted SQLite database ensuring secure storage of sensitive NHS content and user data. Built robust data synchronisation engine handling thousands of NHS articles and multimedia content with intelligent sync strategies and conflict resolution.

Location-Based Services: Built comprehensive NHS facility mapping system displaying local healthcare locations, hubs, and services with real-time facility information including opening hours, contact details, and available services. Implemented geolocation-based facility discovery helping parents find nearest healthcare resources.

Local News Integration: Developed location-aware news aggregation system pulling content from local GP websites and healthcare providers. Built geographic content filtering based on user-selected regions (Liverpool, St Helens, Cheshire, etc.) with automated content scraping and parsing from multiple local healthcare sources.

CMS Integration: Seamlessly integrated with custom Damibu Feeds CMS for culturally-adapted content delivery, implementing dynamic content loading while maintaining offline functionality and building content caching mechanisms ensuring users always have access to latest NHS guidance.

Impact: Serves families with reliable, culturally-sensitive healthcare guidance. The intelligent notification system ensures parents receive relevant information at optimal developmental stages, while offline functionality provides critical access regardless of connectivity. Strengthened family healthcare decision-making while promoting child wellness through culturally-aware, developmentally-timed guidance that builds parental confidence and improves health outcomes.

My House Of Memories

The Challenge: National Museums Liverpool needed to digitise their acclaimed "House of Memories" dementia support program to reach more families.

Serverless Backend Architecture: Architected serverless backend using AWS Lambda for handling concurrent synchronous tasks and content processing. Built scalable content processing pipeline capable of handling multiple package generation requests simultaneously with robust error handling and logging systems.

Content Package System: Developed sophisticated content packaging system enabling creation of region-specific and language-specific dementia support materials. Built flexible object and package creation workflow allowing museum staff to tailor therapeutic content for different communities with content versioning and package management.

Multi-Regional Distribution: Created S3-based distribution system where packages operate independently during system outages. Built content localisation framework supporting multiple regions and languages, with content inheritance system allowing regional packages to share base content while adding local customisations.

Cultural Heritage Integration: Collaborated closely with cultural heritage experts and dementia care specialists to ensure therapeutic value preservation. Built content import/export systems enabling integration with existing museum digital archives with comprehensive audit trails and version control.

Impact: Extended reach of vital dementia support services through digital innovation. The platform's self-contained package system enables deployment to communities without reliable internet infrastructure, significantly expanding access to dementia care resources. Improved care experiences for patients and families while advancing public dementia awareness, making this opportunity to be trusted with such meaningful healthcare work particularly rewarding.
