WordPress+Laravel Dev for SaaS Travel Platform

Job ID: 40430791

Budget: $1,500 – $3,000 USD

Senior Full-Stack Developer for Private SaaS Travel Platform (WordPress + Laravel + PostGIS)

Description:
I am looking for a senior full-stack developer or a highly skilled team for a long-term partnership. The goal is to build a high-performance "Master Build" for my main tour agency site (joinexcursions.com) and a centralized Laravel-based backend ("The Brain") to manage up to 10 domains.

Core Requirements:

1. Frontend (WordPress):

Migration to WP Travel Engine Pro using Gutenberg (Strictly NO Elementor).

SEO Security: 1:1 URL mapping for 250+ tour pages to ensure zero ranking loss. Preservation of Schema.org (TourPackage) markup.

Performance: Minimum 90+ PageSpeed score on Mobile. Infrastructure includes Vultr high-performance hosting and Cloudflare (Paid version).

Media: All images must be converted to WebP before migration.

2. Backend Brain (Laravel 11 + PostgreSQL):

Multi-Tenant Architecture: Manage 10 sites from one centralized dashboard.

Geospatial Logic (PostGIS): Implement high-speed polygon detection using GiST Indexing and ST_Contains queries. The system must automatically find the correct 'Pickup Time' based on the hotel's coordinates inside custom-drawn polygons.

Advanced Accounting: Automated tracking of supplier ledgers (net cost), profit calculations (Selling - Net), and staff commission tracking.

PDF Automation: Automated generation and email dispatch of PDF tickets and invoices upon admin approval.

3. Integration:

Real-time booking synchronization between WordPress and the Laravel Brain via secure REST API and Webhooks.

Deliverables:

Fully functional Master Site + Centralized Dashboard.

Staging environment for testing.

90 days of post-launch technical support.

Full ownership of the source code.

Note: Please mention your experience with PostGIS and Multi-tenant systems in your proposal. I am looking for an architect who can out-engineer a SaaS platform
