TUI Poland needed a faster, more reliable, and client-oriented mobile app. However, their existing legacy application dealt with thousands of customer operations daily. A big-bang style legacy modernization was out of the question, as it would force TUI to compromise on their business.
We researched the client’s needs and plan long-term accordingly. It took our team almost a year to rewrite the legacy application code. After running a UX/UI audit, we also redesigned the app’s interface to become more user-friendly. Since then, we have been implementing new app features. Thanks to the successful refactor, TUI is now the leader of travel applications in Poland. See full case study
