Full-Stack WordPress Engineer: Dual US/AU HIPAA & AHPRA Site with GeoIP Routing

PROJECT OVERVIEW I am looking for a full-stack WordPress developer or agency to build a website for a single mental health brand that operates across two international jurisdictions: the United States and Australia. Because of strict healthcare advertising, title protection, and licensing laws in both countries (AHPRA in Australia and HIPAA in the US), the site must dynamically adapt its legal terminology, content, and scheduling infrastructure based on the visitor's location. CORE TECHNICAL REQUIREMENTS • GeoIP Sub-Folder Routing: The site needs to automatically detect a user’s IP address at the server level. US visitors must be routed to /us/ (featuring "Therapy" branding/language), and Australian visitors must be routed to /au/ (featuring "Psychology" branding/language to comply with AHPRA rules). • International SEO: Correct implementation of hreflang tags so Google indexes the correct country-specific pages for the right audiences without duplicate content or canonical penalties. • Dual Practice Management Integrations: Based on the user's location, the "Book Now" buttons and contact forms must dynamically route data to separate, secure platforms: • US Traffic: Must route securely to a US-compliant system (e.g., SimplePractice). • AU Traffic: Must route to an Australian-compliant system (e.g., Halaxy or Cliniko). • Data Compliance: The backend, hosting environment, and form handling must be strictly built around both US HIPAA guidelines (including BAA agreements for forms) and Australian Privacy Principles. • Clean Gutenberg/Block Architecture: Custom-coded themes using lightweight blocks. No bloated pre-made templates or heavy third-party page builders (like Elementor or Divi). WHAT I AM LOOKING FOR An experienced backend or full-stack developer who understands edge-level server configuration, secure API integrations, and international web architecture. PLEASE REPLY WITH: 1. A rough timeline estimate based on this scope. 2. 2-3 examples of live websites you have built that feature either multi-regional/geolocation routing or complex API integrations. To ensure you have actually read this entire brief, please start the very first line of your proposal with the word: Geo-Split.
