Workflow & processes

Here we agree to provide specific software services (requirement specification, design, development, QA), that your project needs for a specified price or price range. There is a start and end date of the project and we have well defined requirements and technologies, which can’t vary during the time of the project.

Melita Ltd.


MELITA LTD (customer 360, myMelita, eSHOP, MaltaPay, ModemInfo, Itaps)

Melita LTD, Malta’s biggest telecom is operating in the field of mobile telephone networks, fixed lines, internet, Wi-Fi, and TV. Based on a long-term support relationship (more than 2 years of partnership) we are implementing new software, adding new functionalities and integrating existing systems. These are some of the things we worked on: integration of a CRM system with the Call Center Systems, a self-care mobile and web applications, an eShop integrated with an Ordering and Logistics system, a system for top-up of pre-paid mobile services, a software for remote identification and solving of issues with home devices.

Customer 360-degree overview

The system provides a holistic condensed customer overview to agents handling customer requests (answering sales enquiries, scheduling and fulfilling new orders, addressing customer complaints and difficulties). The goal is to present key essential information from the various BSS subsystems on one screen, so service levels are improved.

Melita’s CRM system provides accounts receivable, invoicing, offers and products, contracts and ordering related information. The CRM exposes a number of SOAP APIs enabling the retrieve of structured data.

Additionally, customers’ issues are logged and managed to resolution via the RT ticketing system. RT provides a REST-like interface for integration purposes.

Customer impacting outages are registered and tracked via a Melita’s developed interface and control layer with an RT back-end (outages are handled as tickets in a special queue). Both our Call Centre IVR and Self Care portal (App and Web) query this REST interface to identify current outages specifically affecting the calling customer/self-care user.

A Wordpress-based help-center is used to assist agents in addressing the most common issues. Help articles are retrieved using key words and tags via a JSON based interface.

An Operational DWH also provides customer related measures such as ARPU, household and account holder relationships, customer loyalty. This functionality is available through an SQL interface.

An external credit rating agency is used to assess customer credit worthiness. A SOAP interface is provided.

Technologies Used:

  • Java & Java Spring
  • Spring MVC
  • Spring Security (for SSO and ACLs)
  • API integration (REST, SOAP, JSON)
  • SQL
  • JavaScript, Angular JS

eSHOP 

This is a long-term project allowing customers to upgrade their existing services and purchase new add-ons. Integration to the Amdocs ACC Ordering subsystem is essential here – APIs are available to retrieve current promotions and add-ons, submit orders, evaluate eligibility and disallow downgrades, accept deposits, evaluate credit rating. The main challenge here is working in an asynchronous mode with asynchronous APIs.

Technologies Used:

  • Java & Java Spring
  • Spring MVC, Spring Security, Spring Boot
  • API integration (REST and SOAP)
  • Messaging – Apollo MQ, STOMP, GCM, SMPP, SMTP
  • Javascript, Angular JS, JQuery
  • HTML5 and web sockets
  • SQL

Maltapay

Our team created two web services ValidateTopup and ActionTopup for processing pre-paid cards. The customer presents the verification number code from the pre-paid card, which has to be confirmed. ValidateTopup validates the number, the cash provided by the customer and informs if the mobile pre-paid top-up process should proceed. All top-up attempts are first authorized through this web service method before any action is performed. ActionTopup is performing the actual top-up, following the authorization via ValidateTopup.

Technologies Used:

  • Java & Java Spring
  • Spring MVC, Spring Security, Spring Boot
  • API integration (SOAP)
  • MySQL

“Thank you for the great job, guys!”

City Stories


City Stories is an interactive native mobile (Android & iOS) application – a GO Game about completing quests in real-life environments. Each quest consists of tasks which the user needs to solve in order to proceed to the next quest.

This long-term project consists of four parts – an Android App, iOS App, API and Admin panel. To be able to discover and buy quests, the users should be registered and logged-in.

The quests are related to real-world locations and specific for different cities. To achieve this functionality, we used Google Maps for Map implementation.

The first phase is with a single-player mode. It is lightweight and works fast on all Android devices above version 4.4 KitKat. The game provides the best possible performance and user experience to satisfy and encourage users to make another purchase – a new quest or to replay an old one.

Another interesting feature of the app we implemented is the Augmented reality (AR). With the help of advanced AR technologies, we made the information about the surrounding world interactive and it can be digitally altered. Parts of the real environment and its objects can be overlaid in real time. The searched object (described in the specific quest) can be scanned. It is registered, recognized and verified so that the user can continue to the following task. Free hints can also be received via the AR functionality.

Technologies Used:

  • The backend API is designed and developed on latest JAVA & Spring framework
  • The game is developed as native Android and iOS applications
  • Google Maps is used for Map implementation.

Here is what CityStories’ CEO has to say about working with us:
