We are working within the whole Software Development Life Cycle process starting from VCS and up to production deployment

We've different projects:

  • Development, where we implement build process including build framework configuration using Maven, Gradle, FASTBuild, premake, etc. as well as test run automated configuration, development and production environment deployment, configuration and maintenance.
  • Infrastructure Management - bare-metal, cloud environments and hybrid of course.

Among other things we have shared infrastructure services between our projects across 3 branches and managed by our division. We have a virtualization cluster which contains GPU-optimized hardware for game assets builds, lightning and object physics calculation besides high-performance regular calculation nodes. KVM is the heart of our cluster managed by oVirt.

Our infrastructure services catalog contains both vital for SDLC services like build scheduler Jenkins, binary artifacts management Sonatype Nexus, C/CPP dependency management system Conan, Static Code analysis tool Sonarqube and infrastructure configuration management SaltStack, Zabbix monitoring services, log management by ELK Stack, build slaves Docker Swarm cluster and old-school PXE of course=)

All infrastructure services managed by SaltStack Formulas which we have more than 100 starting from NGINX and up to very project-specific services like Kurento Media server, OpenVAS. We've well-formed security techniques using SELinux, local firewalling, port-knocking and socket activation techniques, Intrusion Detection Systems, penetration and out-of-service testing, etc.

Infrastructure configurations has their own release cycle contains development, pull-request review, integration testing for two major platforms CentOS/Debian at least, versioning, binary artifact packaging and finally deployment into production environment. Well-formed release cycle helps us to catch configuration bugs at earlier stage.

You'll learn not only development and production lines administration and maintenance, private and public cloud infrastructure management on major platforms like AWS and Azure, SDLC process establishment from scratch, distributed build process techniques, build frameworks configuration for C/CPP, C#, Java, JS/TS, PHP, but not limited by this list, languages as well as participate in formation/refactoring of project architecture.

Since our division established as service you wouldn't work only with one but with all projects.
