Our customer from the UK came up with a new interesting algorithm that should help people to find the work of their dreams, and help employers to find the best employees.

It was decided to develop the project on Meteor. This framework is designed for rapid development of web applications, which is achieved through the use of JavaScript not only on the client side, but also on the server side. Also, it is achieved by simplifying the client-server communication. MongoDB - the standard choice of the data storage for Meteor.

This allowed us to develop the application in the shortest possible time, concentrating our efforts on functionality.

https://www.iesohealth.com/en-us

A large British company performing process automation in the healthcare contacted us with the following task. In their business they have to deal with a lot of processes. Over the years, the processes have become overly complex for understanding and support. Therefore, they decided to use Microsoft Workflow Foundation to manage the processes.

To simplify the development of workflows, a visual editor has been created. The editor was developed using WPF with use of MVVM Prism framework. In addition, the editor allowed to remotely debug workflows, as well as visualize the progress of the processes recorded in the log.

For execution of work processes, a server part was developed with support for remote debugging. Particular attention was paid to the possibility of remote real-time debugging, detailed logging of processes, with the possibility of subsequent visualization of the recorded process, as well as recovery from a failure.

All client and server code were 100% covered with unit tests.

http://gis.magazinmagazinov.ru

We were contacted by a large Russian consulting company performing analytics in the area of shopping center construction. The task was to develop a web application for calculating and visualizing transport accessibility zones for outlets.

Existing geospatial products for creating transport accessibility areas didn't fit customer's needs due to low speed and/or precision, so we get open-source product OSRM and created fast and exact algorithms for building isochrone zones on it's basis.

To build analytics model on the basis of customer's formulas we added methods for fast competitor's search within zones, for population calculations, etc

As address search engine we decided to use OpenStreetMap's search engine "Nominatim"

These products require Linux platform, so we decided to use Mono and MySQL for development.

For working with maps, the LeafletJS framework was chosen. This allowed to use Yandex.Maps, Open Street Maps, various cadastral layers, heat maps, etc.

Investor profiling application

Our customer, a large Russian investment company, contacted us with the task of modernizing one of their web applications. It was a small web application for customer questioning and their automatic classification. The application is integrated with other systems via the BizTalk bus.

The application was written in ASP.NET 2.0, and all its logic was encapsulated in the stored procedures of MS SQL Server. As a part of the infrastructure modernization strategy, it was decided to rewrite this application and, at the same time, to try the modern technologies of the Microsoft stack.

  • The client part of the new application is developed using React + Redux binding and is a Single Page Application (SPA). The main programming language for the client part is TypeScript.
  • The server part is a REST service developed on .NET Core.
  • MS SQL is used as a data storage.

Back office for investment company

For many years we have been working to support a large information system. This is a complex system with a long history. Over the years, it has become clear that it is becoming more and more difficult to maintain it. That is why it was decided to develop a prototype of a new system implementing a part of the functionality with use of modern technologies.

The Single Page Application DurandalJS framework was chosen as the basis of the client part of the web application. To build user interface, DurnadalJS uses the MVKM framework KnockoutJS - one of the best SPA frameworks in its time.

It was decided to develop the server part using cross platform .NET Core framework, just released then from Beta stage

Now we can conclude that .NET Core has met all expectations and is perfectly integrated into microservice architecture as a cross-platform solution. But we switched from DurandalJS to SPA frameworks of the new generation, such as React, mostly because of support of modern JavaScript standards and TypeScript programming language.

Technologies: .NET Core, DurandalJS, KnockoutJS, Bootstrap, MS SQL Server, EntityFramework, HTML5

Automation of emergency dispatchers

The software complex automates the emergency dispatchers services operating in many cities of Russia. The complex includes:

  • Automated dispatcher workplace - web application developed on DurandalJS, KnockoutJS and Bootstrap. The application allows dispatchers to track reports of new accidents in real time and coordinate the actions of emergency commissioners
  • The server part of the complex is developed on the platform. NET Core and provides a REST interface for both dispatcher's workstation and mobile applications (iOS and Android) of emergency commissioners
  • SignalR plays a significant role in this complex. PUSH notifications are not enough to transfer data about new accidents to mobile devices of emergency commissioners in time and reliably, as well as to the dispatchers' interface. SignalR solves this problem and helps employees of our customer to arrive at the scene of the accident first.

Real-Time Lotus Notes and RDBMS Integration

One of the most actual tasks in the enterprise IT infrastructure is to organize single data access point based on data received from heterogeneous sources: from Lotus Domino documents, relational databases, ERP systems, etc. One of the most popular solutions in this case is creation of a common data repository based on some RDBMS. Usually, such repositories are organized using one of the most popular relational databases, like MS SQL, MySQL, Oracle, etc. The main goal of creating such single common storage is ability to create reports, which consolidate data related with different business processes and their phases within the enterprise.

We have created a product for efficient transfer of data from Lotus Notes and Domino into SQL in almost real-time. The product has few advantages compared to its competitors.

Below is the list of main product features:

  • Flexible transfer of data structures of any complexity. To transfer Lotus Notes data the built-in @formulas are used, which are well known by any Lotus developer or administrator. For each form, user can define 3 @formulas for each of the events INSERT/UPDATE/DELETE. These formulas in fact define a SQL query, which will be executed when processing corresponding event for a particular document.
  • Data transfer is performed almost in real-time. A monitoring module, which is implemented as Lotus Domino database hook add-in, triggers data transfer as soon as a document is changed in Lotus Notes.
  • Persistent queue. Lotus Notes database is used to store the information about modified Lotus Notes documents, which is, in fact a persistent queue. This eliminates the risk to miss any document changes, for example, during SQL server downtime, which potentially may cause Lotus Notes and SQL databases to be not in sync.
  • Data transfer module. It is executed as the Domino server task and provides timely transfer of data for documents, which were put in the queue by the monitoring module.
    • Insertion or updating of any number of table rows, both for single-value fields, and multi-value fields
    • Deletion of table rows
    • Creation, modification and deletion of SQL database tables
    • Execution of stored procedures on the SQL server
    • What's important is that all operations are executed in the single transaction.
  • High data transfer rates. The speed of data transfer on a typical configurations of Lotus Domino and SQL reaches dozens thousands operations per minute. This speed is achieved by using Lotus C API when accessing Lotus Notes data.
