CLIENT BACKGROUND MyJet app is a new generation of back office eco-system created by JetSoftPro team. An integrated platform for managing your work performance, MyJet easily adapts to the needs of every employee. Speed, ease of use and reliability make MyJet app an effective tool in corporate daily work. BUSINESS CHALLENGE We needed a corporate mobile application that would unite functions from different corporate systems HRMS, time tracking, financial system, chat, etc., so employees have in their phones all necessary information and functions related to their work in the company. It has to back employees up in situations when they are out of computer. SOLUTION We created an app MyJet, that is already integrated with our HRMS’s data base. We developed API for this integration, and employees have their own profiles with personal information, they can see their own available leaves, search the list of all employees and see colleague’s contact information. Also, we have a hardware part which is connected to the office door. Our employees can open office doors with the help of MyJet application and hardware combination so there is no need in carrying keys for that. PRODUCT OVERVIEW One of the most interesting and popular features is the ability to open the office door from your phone / app. This was done using the AWS Amplify IoT Core service. The application communicates with a real device that receives signals to open the door through the IoT Cloud service. The device for opening the door is based on a microcontroller with a Wi-Fi module, and controls the relay responsible for opening the door. The cloud service operates on the MQTT protocol, which is specially designed to support unstable connections. The exchange of data between the service, the application and the devices is encrypted and is initiated only after verification of identification, so this link is also very well protected. Also one of the main functions is close integration with the internal HRMS, which allows the user: request vacations and view available vacations see and change your data be able to communicate with colleagues log time download documents and many other features that were previously only available in the web version. The user will also receive notifications about colleagues' birthdays, important corporate news, or changes in his/her status (vacation has been agreed, etc.). TECHNICAL IMPLEMENTATION When creating the application, we focused on security, security of corporate and personal data, and convenience for the end user. The AWS Cognito User Pool service was used for authorization in the application, and since the service is connected to our user directory via SAML-authentication, the authorization in the application is possible only with a working email and password, which makes it impossible for a third party to access the application and also facilitates UX, as you do not need to invent a new login password and use an existing one. To increase security, an additional feature has also been introduced to install and verify the PIN code, which is re-installed each time you log in (if the user logged out) and is not tied to the device PIN code. The user cannot avoid setting the PIN code. Further access to the application is possible only after entering the PIN code or after undergoing biometric authentication (if it is available for this device). If necessary, you can change the PIN code while using the application.
