Web-platform with 4,120,000 locations on the map

There was an outdated version of the system. It was difficult to find developers for the obsolete technology (ASP.NET). At the same time, it was important to start adding new functionality in the shortest possible time and bring them to the market. An additional problem was slow operation of the system (loading of the pages took more than 10 seconds), users #ooded support service with messages. Also, the data in the system was incomplete, it was necessary to integrate with the new data providers. This, in turn, has led to a point increase on the map by 2 times. The time was limited. We transferred the system to modern technology within 4 days. The number of users increased, and the number of calls to the support service fell to 2 per day after 3 weeks. We added 4 million objects to the map. We optimized the speed of loading pages from 10 seconds to 1 second without changing the hardware. We updated the map to the latest version. We implemented new functionality in a quiet mode during 7 months. We added support for mobile devices. Team size: 4 Developers, 1 QA and 1 Project Manager

Learning Management System (LMS)

It was necessary to develop a learning management system. The system have to include webinar rooms, an assessment center, and a system to upload/modify courses, monitoring the progress of students. It was necessary to develop the product iteratively, releasing a new stable version every 4 weeks. As a development methodology, SCRUM was selected with an iteration of 2 weeks. At the end of each iteration, a demonstration was carried out to customers and users. The team was to consist of 7 developers, 1 designer, project manager and 2 testers. As a technology platform, a platform from Microsoft (.NET) was taken. It was decided to maintain the widely used SCORM standard in the system. This would allow new customers to easily transfer their courses from their old platform to our new one. Team size: 7 Developers, 2 QA, 1 Web-Designer and 1 Project Manager.

Highload Data Validation System (750,000 messages per minute)

The solution is supposed to validate XML messages from 5 di$erent sport data services. There were screens to set up validation rules, rules consisted of di$erent operators and AND, OR logic. We had challenges with performance, because maximum loading was 750,000 messages per minute. We created di$erent applications, some of them were downloading XML less, other ones were validating them and were working in parallel. The solution also contained screens with statistics charts and XML messages with the wrong data. Team size: 2 developers, 1 QA and 1 Project Manager. The project was critical and had a tight timeline.

Customer support platform in 8 weeks

Solution supposed to get tickets from information system customers. It was able to create rules to assign tickets to appropriate departments based on di$erent conditions: priority, product, issue type, etc. The system had customisable ticket forms with custom fields of 7 different types. Timeline for the project was very tight, basically we had 8 weeks to get the system implemented. Because of that we had to create solid architecture with reusable components to get it done faster.

Web platform for architectures

The challenge was to provide high performance and smooth user experience. WebGl was new at that time and there was little documentation available. The system allowed architectures to apply different materials in real-time and rotate the 3d model of a house. Also we used ASP.NET MVC on the server side and AngularJS.

Web application - Form Editor

A modern web app to construct forms. The outcome was supposed to be "modern", meaning that we had to work with the most trending frameworks. We chose ASP.NET MVC, Angular JS and Angular Material library for UI. There was a lot of drag and drop functionality. End user was able to take an element (text box question, radio button question) and drag it to the central area. Team size: 2 Developers, 1 QA and 1 Project Manager
