TUI Digital Assistant (TDA)

During 2014 ‐ 2017 we worked for TUI in London at the "TUI Mobility Hub". Joining their development team, we maintained, developed and contributed to four of their core TDA (TUI DIGITAL ASSISTANT) apps for both Android and iOS phones, plus two newly developed apps specifically designed for tablets. Built using an enterprise instance of the Titanium framework, including Node.js middleware API layers, our work spanned products that catered for three different regional markets from the UK, Germany and the Nordic regions.
