JalSentry
An environmental decision-support MVP, built at a hackathon, that combines live weather signals with community incident reports.
The problem
Weather data alone doesn't show what is happening on the ground. Community reports alone are hard to act on. JalSentry puts the two side by side.
Technical approach
Live weather signals and community incident reports feed a deterministic 0 to 100 risk heuristic, running on AWS Lambda, API Gateway and DynamoDB.
This case study is still being written. Architecture, trade-offs and lessons will be added as they're documented.
