Web-server applications development

In most cases we use apache, nodes and Nginx/Tengine powered web servers. We use Php, Python, Perl, .NET, Ruby (Ruby on Rails), JavaScript and Lua according to the functionality that we have to implement. For example, we can use different technologies to create better solutions such as long-running for real-time data exchange and so on. Additionally, we can use the J2SE/J2EE technology stack (JSP/EJB/Spring, Hybernate, SiteMash, Spark/Jetty) technologies for web-server building in Java or modification/upgrade of existing Java-written software systems.

Cases

Paypong

Technologies

.NET, Microsoft Windows Server, NGinx, MS-SQL, Bootstrap, RabbitMQ, SignalR, Angular.JS, TeamCity, Git, REST api, Multithreading

Scenario

The system was integrated with the payment gateways of several banks, service providers, internal credit management system, also there are plans for the b2b feature segment development.

By August, 2017 the system was unstable, the situation demands regular developers intervention to correct numerical errors and investigate incidents. Up to 30% of the time of our team was spent on support tasks and operational bug fixes.

Thus the client is dissatisfied with the quality of services, which were provided by the current team for developing and maintaining the system. There are also concerns about the overall quality of the created architecture and code.

World of Crew

Technologies

Object-C, Swift 4, PHP+MySQL, Nodejs, Firebase, Java

Scenario

Start-up that is in “proof of concept” stage started investing in software development as early as in 2016. At the beginning of 2017 the software development stopped because of incompetency of the current technical team to stabilize mobile app builds and publish them. The founder of the startup decided to change the team. Then set a task for a new team to prepare a minimal core functions for release and enter the market no later than 2 months after launching.

Gol+Pas

Technologies

Linux, Apache, MySQL, PHP7, PostgreSQL, Python, Delphy, RabbitMQ, Swift, alamofire, moya, mbprogresshud, JavaSE, Kotlin, retrofit2, rxjava2, dagger2, android jetpack components, JS

Problem

The game portal had a huge number of automatic content checks. The information derived from scanning was used to get advances in gambling.

OnlyOriginal

Technologies

Postgres, Java2ee (jdbc+spring), Openresty, Javascript (vue.js, npm), html5 f/e, linux/ docker runtime, react-native mobile

Scenario

The client requires the development of technological solutions, which would effectively counteract the spread of counterfeit goods on the market. During the strategic session a vision was developed for problem solving, which was based on the idea proposed by a representative of Codein Software, who was invited as an expert in modern technologies.

During the work on the project, it allowed the Codein team to call out the best professional qualities and create a modern technologically accessible product.
