Distributed Tasks
Highlights
- LLM pipeline generates children's stories with age-appropriate content
- Multimedia creation: text, images, and animations combined into animated books
- Microservice architecture with FastAPI backend and distributed task processing
- React Native app published on iOS App Store
- Color-following text UI to assist children with reading
Features
Story Generation
Multi-step LLM pipeline that creates age-appropriate narratives with characters, plot arcs, and moral lessons.
Animated Books
Stories rendered as interactive animated books with illustrations and page-turn animations.
Microservices Backend
Python/FastAPI services handling story generation, image creation, and book assembly as distributed tasks.
Reading Assist
Color-highlighted text that follows along as children read, helping them track words and improving reading comprehension.
Challenges & Learnings
- Designing a child-friendly UX that young kids can navigate intuitively
- Publishing the app on the iOS App Store for the first time — navigating review guidelines and provisioning
- Ensuring LLM output was consistently safe and age-appropriate for children
- Coordinating multiple async microservices (story → images → assembly) with reliable error handling
