OTA Platform: Flights Cars Hotels -- 2

@kamran2012

Hi there, I will deliver your OTA platform — unified search and bundling across flights, hotels, and cars, agent portal with markup control, admin panel with LMS/CRM/rule engine/coupon engine, and the closed wallet payment system with channel-specific convenience fee rules. For the supplier aggregation layer, I will build each GDS connector (Amadeus, Sabre, Travelport) as an independent microservice behind a normalized response schema — so adding a new bedbank or car supplier means writing one adapter without touching core search logic. Redis caching will sit at both the availability and pricing layers with TTL tuned per supplier SLA to minimize redundant API calls and keep search under two seconds. Questions: 1) Which GDS contracts do you already hold, and do you have sandbox credentials ready for development? Looking forward to talking through the details. Kamran

I have extensive experience in Website Design, Mobile App Development, and React.js, making me a great match for the OTA Platform: Flights Cars Hotels -- 2 project. I am confident in my ability to successfully integrate multiple GDS or bedbank/car hire APIs and efficiently handle supplier connectivity and availability caching. The budget can be adjusted once the full scope is discussed, and I am committed to delivering high-quality results within your budget. Please go through my profile, which showcases 15 years of experience. Let's discuss the job details and get started right away. Looking forward to hearing from you.

Hi there, Hope you are doing well. I’ve worked on large-scale travel/booking platforms with multi-supplier integrations, including handling GDS/bedbank-style APIs, aggregation layers, and caching strategies for high-performance search and booking flows. I understand the complexity around availability, pricing sync, and unified cart systems across flights, hotels, and cars. For your platform, I can take ownership of: GDS / supplier integration layer (Amadeus/Sabre/Travelport or similar APIs) with modular connectors Aggregation + smart caching (Redis) to optimize response time and reduce API costs Unified search + bundling cart across multiple services Wallet + payment system with rule engine (fees, B2C/B2B/corporate flows) Admin + agent portal with role-based access, reporting, CRM, and campaign tools My approach for supplier connectivity: Build a connector-based microservice layer (NestJS) where each supplier (GDS/bedbank) is isolated Normalize responses into a common schema for flights/hotels/cars Implement intelligent caching + fallback logic for availability and pricing Add config-driven supplier management, so new suppliers can be added without code changes I focus on building scalable, production-grade systems, not just features—especially important for OTA platforms. I can also walk you through a clear architecture before starting. Best regards, Dinesh

Hi there! I'm Asma, a web developer and graphic designer with 10 years of hands-on experience helping brands stand out in crowded markets. I've worked with clients and agencies across fashion, hospitality, property, and luxury lifestyle sectors, and one thing stays constant: I'm obsessed with getting the details right. I don't just make things look pretty. I solve problems. Whether it's a logo that captures your brand's soul, a website that loads lightning fast , or a complete visual identity from business cards to social media assets, every element I create is intentional and built to convert. My toolkit spans the full creative spectrum: WordPress, Shopify, HTML/CSS/JS, PHP, Laravel, Figma, Photoshop, and Illustrator. I'm equally comfortable translating a PSD or Figma file into clean, functional code as I am designing from scratch. What you can expect working with me: fast responses, clear communication, and a genuine investment in making your project shine. I treat every client's vision like it's my own. I'd love to learn more about what you're looking for. Let's create something remarkable together. Looking forward to hearing from you!

You need a full OTA platform with unified search, bundling, and secure user management, plus agent and admin portals—built as a modular microservices system. From my experience delivering OTA projects with Amadeus and Sabre integrations, I know how complex managing and syncing multiple GDS and bedbank feeds can be. I would start by designing a flexible aggregation layer that normalizes supplier responses into a common format. For caching, I suggest using Redis with smart invalidation based on supplier data change frequency to keep search fast without unnecessary API hits. Supplier config panels can then load connectors dynamically to add new sources without development effort. For payments, I’d build the close wallet system as separate microservices with strict role-based access and transaction rules linked to product attributes, supporting all customer and agent types securely. Would you prefer REST or GraphQL for front-to-back communication? And do you have any preferred suppliers beyond the main GDS/bedbanks? I’m ready to build a clear, scalable architecture that simplifies supplier integration and user workflows and get your staging setup with full docs and training done fast.

@RajAbhisek

Hi, We've worked on OTA platforms with GDS integration. Amadeus and Travelport specifically — flight search, PNR creation, ticketing, fare rules, seat maps. On the hotel side we've worked with bedbank connectors where the challenge is always the same — response time and cache management. We solved that with Redis layers and async polling so the UI never feels slow even when suppliers are. Your architecture makes sense to us. NestJS with microservices is the right call for something this modular. Separating the supplier connectors behind an aggregation layer with a config panel — we've built something similar where the client could onboard a new supplier without touching code. The wallet system with separate B2C, B2B agent, and corporate buckets with a rule engine for convenience fees — we've built credit and wallet systems before. Not identical to this but the logic is close enough that we're not guessing. One thing I want to flag — this is a large scope.. We'd want a scoping call first, then a phased delivery plan. Happy to jump on a call this week. Regards, Raj Abhisek

@GenePauly

Hi, This is Gene from Luxembourg. You need a serious OTA platform with flights, hotels, cars, wallet flow, and admin/agent tools built on a clean architecture by someone who already understands GDS and supplier-side complexity. I’d build this in clear modules so search, booking, cart, payments, supplier connectors, wallet, and admin flows stay scalable and easier to maintain as you add more suppliers and channels. I’ve worked on large booking and API-driven platforms, and I understand the importance of caching, fare consistency, supplier failover, and structured integration planning for this kind of system. Which GDS/bedbank/car suppliers do you want connected in phase 1, and which ones are planned for phase 2? Do you already have the wallet, rule engine, and payment aggregator logic documented, or should that be designed from scratch? I can start immediately and move fast on the architecture and phase 1 setup. Best regards.
