Build B2B Data SaaS (Lusha Clone)

We are building a B2B data intelligence platform and already have the core data sets ready for integration. We need an expert developer (or small team) to build the web application using the TALL Stack. The platform will allow users to search for prospects, manage leads, and export data to external CRMs.

Specific Technical Requirements:

Framework: Laravel 11+ with Livewire 3.

Frontend: Tailwind CSS and Alpine.js for highly reactive UI components.

Database: High-performance indexing for the existing data (PostgreSQL or MySQL).

Subscription Model: Implementation of Team-based subscriptions (Seats/User-based billing) using Laravel Cashier (Stripe).

CRM Integrations: OAuth2 flows to export data directly to HubSpot, Salesforce, and Pipedrive.

Extension Support: A backend API designed to serve a Chrome Extension (Manifest V3).

Key Features to Build:

Workspace Management: Ability for "Admins" to buy a subscription and invite "Members" to share a credit pool.

Credit System: Logic to deduct credits upon "revealing" or "exporting" a contact.

Bulk Export: Robust background jobs (Laravel Horizon/Redis) for exporting large lists to HubSpot without timing out.
