Google Maps Service Lead Site

I need a web app that plugs into the Google Maps / Places API and pinpoints potential service-provider leads in any chosen area. The flow is straightforward: users enter a location or keyword, the map displays matching service businesses, and the system captures each company’s customer reviews for later analysis.

The heart of the build is reliable API integration, quick filtering and a compact dashboard where I can read, sort and export the review data. Contact details or full service lists could be added later, but for this first release the reviews themselves are the single non-negotiable data point.

Core deliverables
• Front-end interface (React, Vue or vanilla JavaScript) that lets me search, view markers and browse reviews
• Back-end service (Node, Python or similar) that manages Google Places queries, pagination and rate-limit handling
• CSV export of the gathered review text with basic business metadata
• Deployment on my existing server plus a brief hand-off session

Acceptance criteria: a metro-area search should return results in under two seconds, every review must correspond to the business shown on the map, and API keys must be stored securely.

Tell me your preferred tech stack, timeline and any map-driven projects you have shipped so I can gauge fit quickly.
