We developed the Android app as well as a web-based console for administrators. The app is native and utilises the Parse SDK for back-end data storage. We implemented a Node.js server that takes care of routine tasks and runs complex on-demand operations. We also customised Elasticsearch to index any new entries to the Parse back-end and created a Node based API to respond to search queries from within the application.
Underblu Tech guys are super cool dudes who love their work. They are serious developers of SW and very good in design too - that combination is awesome. Pick their brains for finalising your idea and get your start-up rolled out. All the very best!
