I build complex platforms where multiple systems must talk to each other reliably, especially in hospitality. I co-built approx 120 OTA certified channel managers, artaxnet/innotel (Brazil) and BookAndLink (Indonesia), and have 14+ years of hands-on development across travel, healthcare, education and e-commerce. If your project involves OTA connectivity, real-time data sync, or a multi-user SaaS product that has to work in production (not just in a demo), that's exactly where I'm strongest. HOTEL & TRAVEL TECHNOLOGY • Channel manager development: new builds and new OTA connections • 120 OTA integrations for ARI sync, reservation management, message APi, content/promotion API etc.. • Property Management Systems (PMS) and PMS-to-OTA integration • Booking engines with payment gateway integration • Real-time rate, availability and inventory (ARI) sync, rate parity, overbooking prevention • Reservation systems, price comparison engines, hotel + activity packaging and gift vouchers (built Favotrip for the German and Dutch markets) HEALTHCARE, EDUCATION & SAAS PLATFORMS • Healthcare management platforms (SOCH) with role-based portals for different user types • School management systems covering administration, academics and parent/student access • Multi-tenant SaaS: subscriptions, billing, role-based access control, usage metering • E-commerce synchronization solutions • Legacy system modernization into scalable, subscription-based products API & INTEGRATION WORK API architecture, REST and XML APIs, webhooks, third-party integrations and backend process automation. Integration-heavy projects are the core of what I do. WHY CLIENTS WORK WITH ME • I understand the business logic, not just the code: rate plans, restrictions, mapping, user roles, billing rules • I've taken integrations through third-party certification. • Clear milestones, regular updates, documented code, and support through go-live TECH STACK PHP, Laravel, Python, Node.js, React, Angular, GO Lang, MySQL, REST APIs, XML, JSON, cloud deployment Send me a short description of what you're building or which system you need to connect. I'll reply with an honest take on the approach, timeline and risks.
