We Develop Traveller Apps and GDS-Connected Backends
Engineers who build the apps people use mid-trip and connect them to airline, hotel and tour supplier systems.
We found 30 available Travel App Developers
Travel app developers for the trip and the fares behind it
Cortance helps companies hire travel app developers for both sides of a travel product: the app travelers use mid-trip and the connections that supply it with fares, rooms, and transfers. As of October 2026, our engineers list 30 travel projects.
Nine of those projects ship a mobile app to travellers. Ten connect to an online travel agency, a GDS or a supplier aggregator. We match on the half your product needs most. If the hard part is holds, deposits and selling each room once, our booking system developers cover that work.
What does a travel app handle that a shopping app does not?
A travel app is used away from home, often on roaming data and in a time zone the phone is not set to. A flight time shown in the phone's time zone instead of the airport's sends someone to the gate an hour late. A voucher that needs a signal to load fails at the venue door. Cortance looks for engineers who have shipped apps that carry this context.
Kacper M. took over a tourist app for Ibiza that previous developers had left unstable. Visitors find local vendors on a Google Maps view and redeem offers with a QR code at the vendor. He brought the app to a production-ready state and extended the events calendar and admin panel behind it. Serhii B. worked on an iOS app for finding and booking airport lounges worldwide, with location, reviews and booking on a Node.js backend.
Fares and rooms come from systems you do not run
Most travel products resell seats, rooms and tours that belong to someone else. That inventory arrives through a GDS, an aggregator, or an OTA channel, each with its own format and rules for a valid fare. Airline distribution is changing as well. In August 2025, T2RL counted 210 contracts between airlines and GDSs to use the NDC standard, 124 of them live, running next to the older EDIFACT messaging. A travel backend now has to read both.
Stanislav S. built a data aggregation system for SITA from scratch. It connects GDSs, airlines and third-party platforms for ticket booking and payment, and he ran it in a combined developer and DevOps role. Samir O. wrote AWS Lambda functions that pulled current hotel and condo prices and photos from providers into a booking database on a schedule. That schedule is a product decision: refresh too rarely and search shows prices the supplier no longer accepts.
Where does AI help on a travel codebase, and where does it not?
AI coding tools speed up screens and refactoring. Kacper M. used Claude Code to restructure the inherited Ibiza codebase and build new features, with an AI-assisted review of each change. Travel logic is where a generated change needs a senior reader. That means date math across time zones, fare and cancellation rules, and the mapping of a supplier's response into your own data model. A model writes plausible code for all three, and each one fails only on the trip it did not expect. Cortance looks for engineers who can say which parts of a change they checked by hand.

Three more kinds of travel work our engineers have shipped
A car rental app that opens faster
Danylo Ku. led the React Native app for Renty.ae, a car rental marketplace in the UAE, and cut start-up and load times with lazy loading, caching and API tuning.
Tour search on aggregator APIs
Taras K. built tour search and reservation sites that pull offers from tour aggregator APIs, and tuned the SQL that keeps their search fast.
A transfer app in several languages
Igor G. built features for the React Native app of Pavluks-Trans, a passenger transfer provider, with geolocation, Firebase and several interface languages.
How to choose a travel app developer for your product
A travel product is two systems that have to agree: the app in a traveler's hand and the supplier data behind it. The chapters below cover how to scope the hire, what experience to ask for and how to test it.
Which part of travel is your product in?
The part of travel you sell decides the first hire. Flight search and ticketing needs an engineer who has read fare rules and handled tickets, changes and refunds through a GDS. Stays and rentals need someone who keeps supplier prices and availability current across channels. Tours and activities need aggregator integrations and an operator back office. A traveler companion app needs mobile depth: maps, location, QR codes, push notifications and store releases. Most products need two of these, and Cortance can match them as two engineers or one with both in their history.
GDS, NDC or a supplier API: what experience to ask for
A GDS such as Amadeus, Sabre or Travelport gives access to airline content through one contract. NDC is the airline-direct standard that carries richer offers, such as seats and bags sold together. Hotel, campsite and tour suppliers usually expose their own REST or SOAP APIs. Ask a candidate which of these they connected and what they did when the supplier changed its response. Engineers in our network have worked with Amadeus, with SITA's GDS aggregation and with supplier APIs for hotels, campsites and tours. No project in our data uses NDC yet, and we say so when a brief needs it.
Questions that show travel experience in an interview
- How do you store and show a flight time? A strong answer keeps the local time and the airport's time zone together and shows the traveler local time at the airport.
- What does the app show when a booking loads with no connection? Look for a cached itinerary and voucher, with a clear note on when the data was last updated.
- What happens when a supplier renames a field? The candidate should describe validation at the boundary and an alert, not a blank results page.
- How are prices in other currencies rounded and shown? The answer should name where conversion happens and which amount is charged.
Connect suppliers yourself or start with one travel API?
A travel API aggregator gives one integration for many suppliers and is the faster way to launch; Junction Connect, where Yevhen S. worked, sells flights, hotels, trains, ferries and car rentals this way. The trade-off is margin and control over content. Direct supplier or GDS connections pay off once volume covers the contracts and the upkeep.
What you get when Cortance matches a travel engineer
Cortance is a hiring platform that matches companies with vetted remote developers from its own network. For travel work, we match on the half of the product you need: the traveler app or the supplier connections.

Send the travel brief
Name the platforms your app ships on, the suppliers and channels you connect to, and what breaks today.
- 02
We read travel project histories
We look for the same half of the product in what engineers have shipped: store releases, a GDS or supplier APIs.
- 03
Profiles within 30 minutes
You get matched profiles and interview the engineers you like. Ask each one to walk you through a travel app or integration they kept running.
- 04
Work starts within 2 days
A useful first task is a review of how the app shows times, caches bookings and handles a supplier error.
