I'm Xavier, a full-stack dev with experience in building high-performance prediction market backends and complex data-aggregation services. I’m applying to implement the Featured Markets Endpoint for predictIQ.

Ranking & Discovery Logic: I’ll develop a smart ranking algorithm that weights trading volume, participant count, and time sensitivity to surface the most relevant trending markets directly from your smart contracts.

Performance & Metadata: My solution includes implementing a robust caching layer to ensure the landing page stays fast, delivering complete market metadata (odds, volume, and deadlines) in a clean, paginated format.

Flexible API Design: I'll build the endpoint with TypeScript to support category-based filtering and custom limits, ensuring the top 6–8 diverse markets are consistently served according to your technical specs.
