As an Architect, I have participated in shaping the technical strategy and infrastructure for the organization. My work began with addressing the challenges of resource allocation and cost efficiency. I developed detailed budgeting processes for business applications and resource growth models that enabled the company to support data center expansions, streamline hardware procurement, and analyze expenses with precision.One of my key achievements was the design and implementation of forecasting reports powered by predictive models. These tools transformed resource planning by providing actionable insights, improving accuracy, and enhancing the efficiency of infrastructure management.In addition to these advancements, I led the implementation of IPv6 for the company’s flagship products. This was a critical milestone, ensuring the company’s growth and long-term scalability.As a technical leader, I guided teams in developing automation solutions and Disaster Recovery strategies. These efforts ensured that critical business operations could be relocated seamlessly to alternative sites in case of disruptions, safeguarding business continuity.

As the leader of an international team of 10+ senior engineers, I managed our operations to make sure we had non-stop global support. We managed production across 40+ locations, focusing on maintaining 99.9% availability for key company products.My responsibilities included developing and constructing high-load systems and environments to ensure uninterrupted product operation. This involved creating virtualization clusters, production Jenkins, ELK clusters, Percona, Patroni, RabbitMQ, and Kafka.A significant part of my role was establishing processes for reviewing production-ready services (Cloud Requirements), along with planning and controlling resources (Capacity Planning). I was pivotal in infrastructure optimization, deploying automation, and establishing self-healing systems.I also led the development of process and tool frameworks, including Change Management, Incident Management, Release Management, and Access Management.Key projects under my leadership included:- Adapting SRE practices to our company's realities.- Creating a high-load ELK cluster (Logging as a Service for internal products). - Implementing and creating a Jenkins ecosystem in conjunction with Ansible as the primary system for automation, deployment, and integrations.- Transitioning to N-as-a-Service for databases, logging, infrastructure, and deployment.

As a Senior System Engineer, I maintained our company's infrastructure across over 15 global data centers. My role involved managing virtualization using technologies like ESXI, Virtuozzo, and KVM. A key responsibility was developing and reviewing deployment code using Ansible, including AWX and Jenkins, ensuring deployment reliability. I automated tasks and developed services using Bash and Python, notably creating "Self-healing auto-remediation" services that autonomously fixed bugs and restored services, reducing operational downtimes, improving SLAs, and helping on-duty engineers over night dramatically.In database administration, I handled PerconaCluster, MariaDB+Galera, and Postgresql, focusing on deployment automation and problem-solving. I also managed RabbitMQ, automating deployment and cluster assembly, and oversaw our tech stack comprising Logstash, ElasticSearch, and Kibana. My role included researching technology for our development stack, conducting presentations to solve current issues, and setting service requirements like PoLP and system hardening.Additionally, I contributed to our product's code in Python and Go, demonstrating versatility and technical proficiency.Overall, my tenure as a Senior System Engineer was marked by dedication to enhancing global infrastructure, technological innovation, and a commitment to improving system efficiency, security, and reliability.

As a Lead System Administrator, I was responsible for the daily management and support of our company's project servers, focusing on using Centos and Debian platforms. I excelled in virtualization techniques using KVM and LXC, improving overall system performance. My role included administering a variety of services such as Apache, Nginx, PHP-fpm, Samba, Postfix, VPN, and Mysql. I successfully set up managed Geo Redundancy DNS, minimizing downtime across entire regions by switching loads to nearby data centers.I also took charge of monitoring systems like Zabbix and Icinga, and I developed custom scripts in Bash and Python for system and service detection. My responsibilities extended to managing the Logstash, ElasticSearch, and Kibana stack, as well as configuring Mysql replications and backups. I handled the installation and management of Postfix+Dovecot servers, ensuring full compliance with spf, dkim, and dmarc standards.Furthermore, I was creating and maintaining a 'production like' test environment for developers and implemented Puppet+Foreman in our projects. A key part of my role was led a team of technical experts to upgrade infrastructure, improving internal collaboration and efficiency and actively contributed to the training and development of team members, sharing knowledge and skills.
