Engineering the Backend for a Digital Health Platform

As part of a project under India’s National Health Mission, I developed the backend for a large-scale digital health application designed to improve healthcare accessibility and data efficiency.

Overview

The platform connects health workers, administrators, and citizens through centralized dashboards and analytics. Scalability and speed were key challenges due to massive data inflows.

Core Work

• Developed RESTful APIs in Python (FastAPI)
• Created MongoDB aggregation pipelines for large health datasets
• Integrated React dashboards for reporting and visualization
• Reduced data query latency from 18 seconds to 400ms using optimized indexing and caching

Outcome

The platform handled concurrent user loads efficiently and drastically improved data access speed for field workers and administrators alike.

This project reinforced the value of clean architecture and database tuning in high-impact public health systems.
