At Playrix — one of the leading mobile game developers — I ensure seamless update delivery and enhance release quality through automation, process optimization, and CI/CD improvements.

• Release and Deployment Management. Full-cycle update delivery — from build validation and packaging to store submission.
• Branching, Versioning, and Rollback Management. Oversee branching strategies, version control, and rollback mechanisms.
• CI/CD Pipeline Optimization. Maintain and improve CI/CD processes in TeamCity, focusing on speed, stability, and scalability. Analyze pipeline performance, troubleshoot build issues, and collaborate with the CI team.
• Infrastructure Stability. Monitor and optimize build system performance, analyze crashes and deployment success rates using Grafana.
• Automation and Process Optimization. Develop Python-based tools to eliminate manual tasks in build validation, submission checks, configuration updates, and overall release efficiency.
• Cross-functional Collaboration. Work closely with developers, QA, and CI engineers to establish best practices for build integrity, testing, deployment, and production updates.

Used languages and technologies: Python, TeamCity, GitHub, CMake, Ninja, Gradle

My responsibilities involve managing and maintaining a large-scale, high-load client infrastructure that spans over 800 servers worldwide. Our technology stack is primarily focused on Azure, Linux, Kusto Query Language, PowerShell scripting, and hardware management.

• Monitored and tracked over 30 dead nodes daily, efficiently redistributing recovery tasks and assigning follow-up actions to team members.
• Demonstrated strong foundational knowledge and hands-on experience with Azure networking services (Virtual Network, ExpressRoute), including troubleshooting hybrid connectivity setups and working directly with Software-Defined Networking (SDN) appliances for diagnostics, component replacement, system recovery, and OS/firmware upgrades in coordination with datacenter technicians.
• Created and managed GDCO tickets, collaborating closely with datacenter staff to resolve server hardware issues and ensure minimal downtime. Provided hardware troubleshooting guides for technical specialists from global data centers to enable efficient server recovery operations.
• Restored functionality of ToR (Top of Rack) switches, configured BGP protocols, and recovered node functionality through tailored Linux configuration procedures.
• Designed and implemented Maintenance Configurations for over 200 VMs, automating patch installation and standardizing patch management to ensure security compliance across all servers and VMs.
• Integrated VMs into scalable environments to improve redundancy and mitigate vulnerabilities by developing PowerShell scripts (attaching existing VMs to VMSS configurations, enabling automatic OS upgrades).
• Handled large datasets and developed advanced Kusto Query Language (KQL) queries for infrastructure analysis and reporting.
• Drove automation efforts to reduce manual toil in infrastructure provisioning, scaling, and troubleshooting, resulting in increased operational efficiency and reliability.
• Demonstrated a solid understanding of TCP/IP and data center networking principles throughout all aspects of infrastructure management.
• Substituted for the team lead in their absence: conducted daily stand-ups, ensured project deadlines were met, acted as the main point of contact for delivery and client-side Microsoft managers, and resolved complex cases while assisting team members.

Used languages and technologies: .Net, Linux, Azure DevOps Services, Kusto Query Language (KQL), PowerShell

Played a crucial role with focus on frontend side in multiple projects across various client companies, emphasizing system integrity, user experience, and accessibility. Contributed to the development and optimization of corporate social network platforms and dealership reporting systems, with a focus on enhancing user interfaces, mobile experiences, and software robustness. Worked collaboratively in cross-functional teams, ensuring high software quality standards throughout the development lifecycle.

• Designed and deployed React-based UI modules and integrated new functional parts into applications, leading to enhanced user interaction and enriched feature sets.
• Developed robust parsers and data transformation tools, such as a PDF parser in Node.js, to streamline report generation and presentation.
• Proactively identified and rectified software bugs, leading to increased system stability and performance.
• I actively contributed to code reviews, providing valuable insights and constructive feedback to enhance overall code quality.
• Diagnosed and resolved issues in Azure pipelines, reducing development process delays and accelerating project timelines.
• Worked with network requests and responses.
• Contributed to the transition of legacy logic from class components to functional components in React.
• Prioritized and upheld system integrity, addressing bugs using accessibility principles and automated testing tools like NVDA, Voice Over, and Validator W3.
• Worked with cross-functional teams to ensure quality throughout the software development lifecycle.
• Performed configure Docker and Docker-compose files, CI/CD pipelines to auto-build and auto-deploy.
• Implemented Allure reporting for Cypress tests.
• Developed e2e tests using Cypress framework (JS).
• Developed scenarios for API testing (PyTest).
