01
The Problem
Business Impact
During Covid-19, scientists and IIHMR needed to rapidly collect health survey data from millions of unreported patients. No existing system could scale fast enough or reach enough devices.
Constraints
The app had to be compatible with all browsers and all devices - including old phones used in remote areas - to maximize survey participation.
02
Technical Execution
Architectural Strategy
Built a serverless survey system on AWS Lambda and DynamoDB - designed to scale to millions of responses with minimal infrastructure cost.
Depth of Execution
Simple, unobtrusive design compatible with all browsers and devices. AWS Lambda and DynamoDB chosen for instant scalability and minimal development time. The app scaled on demand to handle millions of concurrent survey submissions.
03
Results
✓Millions of unreported COVID-19 patient surveys registered.
✓Survey data contributed to vaccine research and public health planning.
✓Zero downtime during peak pandemic survey periods.
Future Proofing
Serverless architecture scaled automatically with zero infrastructure management.

Client Feedback
"Adarsh's portfolio already had quite a few good examples of his previous work and thus the bar was set pretty high from the beginning itself. We had very high expectations and yet he somehow managed to exceed all of them. He's a bit of a perfectionist which definitely worked out in our favour. I would love to work with him in the future and would recommend him 10/10 times."
