Build European Heat Risk Dashboard using AI SDK and Aider

Chronic heat waves across Europe are accelerating parametric insurance adoption. You will build a real-time heat wave risk streaming dashboard in TypeScript using Vercel AI SDK and refactor it with Aider. The system must process Copernicus sensor feeds and trigger parametric payout alerts with under 100ms streaming latency.

What you are building

Build a streaming parametric heat trigger application using TypeScript, AI SDK, and Aider for automated risk monitoring.

How work is evaluated

Evaluation

Evaluates the streaming API latency and exact trigger accuracy when climate sensor arrays report extreme temperatures.

Datasets

Public datasets, plus the private datasets you have access to.

How submissions are scored

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

trigger_correctness

Ensures parametric payout matches threshold condition.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

streaming_latency

Time to first stream byte in milliseconds • target: 80 • range: 0-200

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

  • Build real-time streaming interfaces using Vercel AI SDK data streaming primitives.

  • Leverage Aider CLI for AI-assisted code generation and automated unit test refactoring.

  • Calculate threshold breach metrics against high-resolution ERA5 climate data streams.
