Crowfall MMO game environment configuration and maintenance.

AWS cloud based environment configuration and maintenance.

Crowfall MMO game platform environment configuration and maintenance.

Mobile resources management system startup.Lead overall project's services architecture and technological stack. Project and team management as well as team hiring.

Rework CI infrastructure for 3 projects - 2 based on UnrealEngine, 1 in-house proprietary engine.Prepare automated multi-purpose build agents deployment for three major OS platforms, including VM creation on QEMU host from Packer prepared image, automated agents connection into CI system, using Terraform and Ansible.Deployment provides vCPU-pinning, HugePages memory backing, block devices caching and other performance tuning configuration. The number of simultenuos agent deployment limited only by available hardware resources.I've develop Kitchen Ansible provisioner - kitchen-yansible (https://github.com/axmetishe/kitchen-yansible), capable to work with different platforms, provide dependencies management and other features essential to role development process.Wrote more than 30 Ansible cross-platform roles for build agent systems and tools management for MacOS, Windows, Debian, Redhat.Prepared and held Ansible cross-platform roles development and integration testing workshop within the team.In-house proprietary game engine written on C++ were migrated to pure Gradle build, using Native Plugins for 4 platforms - Linux, Windows, MacOS, iOS. Engine's editor uses QT5 framework, which lead me to write QT Gradle plugin for codegen, compile and linkage stages seamless integration with Gradle.This migration reduced build time by 20% without available caching feature in compare with CMake.Projects based on UnrealEngine were migrated to InstalledBuild version, using modified sources and official upstream versions as well, which allow us to switch between versions directly via build parameters without any modifications on build agents.For the InstalledBuild version installers were prepared for Windows and MacOS platforms on order to provide us a way to effectively update engine version across team.Totally reworked LDAP infrastructure deployment using Ansible and Terraform.Developed Terraform modules for AWS management.

Player-coachCreated DevOps division which capable to act at several disciplines - SysOps, NetOps, Releng and DevOps of course.Division with up to 8 people with different grades - starting from Intern and up to Senior.Straight-forward educational process through all grades.Participating at project pre-sale and establishment stages, capable to act as architect.Well known as go-to person for SDLC process as well as for infrastructure and cloud solutions.TechnicalRelease process for UE3/4 for well known game titles. Reduced time from 15h to 2h, there is a room for further optimizations and parallelization.UE3 build Gradle build framework for Windows/Android/iOS platform - from 12h to 1.5h.Wrote FASTBuild toolchain for UE4 UBT which generates bff projects and got 2-times faster builds over open source toolchain. Toolchain is extensible and may be applied for Android and iOS builds.Gradle Native C/C++ compilation descriptor with multi-module project at 100 components and 900 tasks at one of the well known title on the market.Gradle plugin for compiler independent compilation flags at toolchain configuration for better user experience.oVirt managed private cloud with GPU-optimized cluster for workloads like assets compression using CUDA and general computation cluster for regular workloads, able to work with different architectures. Fully-automated test env deployment on AWS, ESXi, KVM for router-specific workloads.Made fixes for several tools like premake-fastbuild exporter, vagrant-libvirt, FRRouting, more than 100 CM configurations for different services, fixes for Jenkins plugins.Manage hybrid environment includes on-premise private clouds and AWS.Whole infrastructure managed by CM SaltStack, including private and public cloud platforms.Participated at core IT infrastructure renewal and personnel education, including virtualization, networking, etc.There are lot of other stuff I did but description field is limited =D
