Tools Used• Ionic• Cordova• Angular• Firebase• Angular-fire• Node.js (script for pushing data into firebase)• Yeoman (for the admin panel)• Git• JavaScript, HTML5, CSS

Resources• Ionic Documentation & Forum• Firebase Documentation & Forum• Angular-fire Documentation• Stack Overflow• Individual blogs on Ionic, Angular and Firebase

Conclusion

Technological Short Comings• Firebase will become very expensive with large database• Google maps direction API• Native app advantage on offline data persistence • Native app advantage on usage of gps technology• Full fledged admin panel• Appointment System - Integration with facilities that already

have IT infrastructure (like Square)

Future Work• Expand database to reflect data not only for Dhaka city but also

the whole country• Explore suitability to convert the hybrid application into a

native application• Consider hardware constraints on different devices• Implement search intelligence to reflect individual user’s

search pattern• Include diagnostic report viewing and transmission facility• Offline availability of data
