EasyHTA: Vaccine Analytics Platform
Interactive Cost-Effectiveness & Budget Impact Analysis Tool for Healthcare Decision Making
Designed and built a complete Health Technology Assessment (HTA) platform to model the cost-effectiveness of vaccination programs. Features a React/TypeScript frontend with an interactive decision tree builder and a robust R backend executing real-time Markov chain simulations via heemod.
Engineered and built from scratch a comprehensive Health Technology Assessment (HTA) platform for modeling the cost-effectiveness of vaccination programs.
End-to-End Development: Solely responsible for the entire software lifecycle, from architectural design and database schema to frontend implementation and backend computation logic.
System Architecture: Designed a decoupled architecture separating clinical parameters from decision logic, utilizing a React/TypeScript frontend for interactive modeling and a robust R backend for running complex Markov chain simulations via
heemodKey Technical Achievements:
Developed a custom interactive Decision Tree Builder with drag-and-drop functionality and real-time validation.
Implemented a sophisticated Facade architectural pattern to synchronize state between disparate data stores (clinical inputs vs. tree logic) without coupling.
Built the mathematical core for calculating ICER (Incremental Cost-Effectiveness Ratio) and Net Budget Impact, ensuring high precision in economic reporting.
Designed the system to be "AI-Ready" by establishing strict typed schemas and stateless computation contracts, enabling future autonomous scenario generation.
