Challenge

The client addressed us with the challenge to create an application that would be an assisting tool in the management of residential complex processes. The key tasks were:

  • Create a single control center for residential complexes;
  • Develop means of communication between the residential complex tenants and the management company;
  • Create an online bulletin board for residential complex tenants;
  • Develop a convenient tool for meter readers transmission;
  • Collect and analyze data received from residents;
  • Create a specific platform for making collective decisions.

Solution

The cross-platform framework Flutter was chosen to create the application, which, in conjunction with Firebase Firestore and Firebase Functions, allows you to achieve a minimum amount of code. The architecture was based on the proven BLoC pattern, which allowed for good optimization and fault tolerance of the application.

Exelor has developed the solution with the following functionality:

  • An application which helps take control over usage of public utility services;
  • checking balances, push notifications about upcoming payments and possible payment arrears;
  • Access to archive data containing information about using public utility services;
  • Showing announcements concerning actual changes in electricity, gas and water supplies;
  • An option of conducting online voting on different issues among the tenants; 
  • Transmission of meter readers by the tenants and data processing by the management company;
  • The ability to send applications to the master about the elimination of various problems related to house management.

Result

The application simplifies management processes of the residential complex, provides a specific database of utility services for the tenants and contains actual information about changes in the provision of utility services as well.

      Documentorum

      Documentorum is a global initiative and a new approach to issuing, registering and validating certificates and diplomas. It has been developed with the use of Hyperledger technology. It enables students to collect all their academic credentials in one place where they are protected against theft and fraud.

      Educational institutions can minimize their costs by using Documentorum for issuing, storing and validating diplomas and certificates. The blockchain technology applied guarantees forgery protection. Documentorum can also come in handy to employers, as it makes pre-employment document check easy and short-length. Above that, it provides the information about candidates’ competences and skills.

      Challenge

      The Exelor team faced a complex task to develop a business solution for creating, storing and validating documents in a convenient and secure way. The technology to choose had to protect the documents against accidental editing or deleting. With paid access to the database, Documentorum had to support instant validation and authentication of the documents.

      It was crucial that the mobile application version of Documentorum could keep all the functionality of the platform.

      Solution

      The team has implemented the following solutions:

      • the blockchain technology Hyperledger that makes storage of documents safe and well protected;
      • the editor which helps to create templates of certificates (graphic module);
      • the mobile application Dart + Flutter SDK which was developed to make it possible to operate your account 24/7;
      • document authentication that is run by scanning the QR code from the Documentorum mobile application;
      • access to the database that depends on the pre-chosen access rights.

      Result

      The users’s digital academic credentials stay perfectly safe as they cannot be deleted or falsified once they are in Documentorum. Besides, they include detailed information about the curriculum and the students’ progress. Documentorum significantly reduces the costs associated with issuing, storing and validating credentials offering a higher level of security and confidentiality in comparison to conventional methods.

        Challenge

        The initial task for the New Line Technologies team was to develop a mobile application for the project. The client has set us the task to create the best and most convenient donation application in the world, with the largest number of users. The client has his own ideas on the app functionality, which we gradually introduced, and offer ours too. Moreover, the project continues to grow very active, and we work on its upgrade and improvement, add new features and expand our collaboration.

        The first challenge for our developers was to deal with the project architecture: we did a code review and refactoring and successfully coped with the task.

        Another field of our cooperation is the design and development of a web application for the project. A large team is already engaged in it, effectively interacting and solving various interesting problems.

        Solution

        To develop an application for Android and iOS, our mobile team has chosen the modern framework – Flutter (Dart language). Today, a user-friendly mobile application allows the fastest donation in under 10 seconds.

        During the work on the project, the New Line Technologies team also implemented such features:

        • A number of payment methods and systems (Stripe, Apple pay, Google Pay, OJC, Plaid, PayPal, Venmo). User can add debit, credit card, bank transfer and more for the most convenient and fastest way to donate. Unfortunately, we were limited in the use of some payment methods due to the particularities of legislation of the industry.
        • Direct donation (by email) without registration. The fastest way to donate.
        • TouchID, FaceID
        • Localizations (now English, Hebrew, Spanish, Russian, and Australian available)
        • Geocoding – provision of actual information to the users, based on their location
        • Referral program, Live Chat
        • Receipts, payment history – for convenient printing and etc
        • Sign in/Sign up via Facebook and Google – integration social network and messengers, social shares
        • Firebase messaging (Push Notifications), dynamic links, remote configuration
          Crashlytics
        • Intercom integration (support chat for customers)
        • QA panel for internal testing
        • Plugin development for Dart, and native (Android, iOS)

        Now we are working on the socialization of the application (the ability to communicate with users and view each other’s profiles), as well as synchronization with friends from social networks (Facebook) and the contact list of the user’s phone

        Our plans and discussions are aimed at further implementation in the Apple Watch and Google Watch apps, and connection of Siri and Google assistant.

        While dealing with the web version of the project, we mostly focused on the direction, where user can monitor donations and campaigns, store receipts, and create a recurring contribution to favorite causes.

        Result

        The main goal was achieved – to create user-friendly, “one-click” donation application, that works with multiple payment platforms, providing connection nonprofits and donors across different countries, languages, and currencies around the world.

        The expertise of our team, effective cooperation, and big idea help to make this project great. Customizable and cutting edge technology bring the charity industry to a new level, creating a better world.

          Where I Am

          WhereIAm is a cross-platform mobile application for fixing the position of another user’s smartphone. The key feature of the application is that location tracking is activated only upon request. This significantly reduces the load on the phone’s battery and thereby qualitatively distinguishes WhereIAm from its competitors.

          Challenge

          The challenge was to create a mobile application for fixing the geolocation of other smartphone users, qualitatively different from its competitors in the following characteristics:

          • free to use;
          • lightweight;
          • energy efficient;
          • high accuracy of geo-positioning;
          • parental control option;
          • real-time geo-positioning option.

          Solution

          Having assessed the client’s requirements, the New Line Technologies team decided to implement this project using the Flutter framework and the Google Firebase platform. This made it possible to avoid writing separate source code for Android and iOS and thereby significantly reduce development costs, and Firebase provided automatic scalability of the application in the future.

          • WhereIAm is less than 34 MB, which is significantly less compared to some popular analogs.
          • The application has a simple and intuitive interface. To launch it, perform only two actions: generate and enter a code for binding smartphones.
          • To prevent possible violations of human rights, the application has an authorization system that allows tracking only after user approval. Thus, two-way location sharing requires the consent of both parties.
          • Available parental control allows parents to unilaterally get the child’s geolocation.
          • Additional functionality for employees is in the process of implementing. It will allow setting working hours and working days for each user, tracking his location during the working time. This solution will reduce the time needed to search for a person in the office. Also, a beacon-device integration will be developed that will help determine the exact room in the office where the person is located.

          Result

          On the one hand, location tracking applications are quite useful for caring for loved ones and children. While on the other, they can be used for unlawful purposes. The New Line Technologies team is pleased to provide in the WhereIAm application an opportunity for caring for loved ones, as well as programmatically implement tracking protection without prior consent from the user.
