At Gazprombank, I operate nine Apache Kafka clusters with approximately 25 brokers and more than 500 topics, while administering Nomad-based platform components including Consul, Vault, ELK, AKHQ and Keycloak. I build CI/CD pipelines, automate Kafka access controls, and created a Go service for certificate-expiry monitoring and alerting.

I've designed fault-tolerant production environments across Yandex Cloud and GCP for a ChatGPT Companion startup, including a highly available PostgreSQL platform using Patroni, etcd, HAProxy and Keepalived. I provision infrastructure with Terraform, automate configuration with Ansible, and run containerized services through Jenkins and GitHub workflows.

At Innotech Group and Altuera, I supported application platforms, delivery pipelines, messaging systems, databases and enterprise contact-centre integrations. My work has included Kubernetes, OpenShift, Docker, TeamCity, Kafka, RabbitMQ, PostgreSQL, Elasticsearch, Nginx and Ansible.

I bring hands-on incident response, fault-tolerance testing, infrastructure automation, technical documentation and cross-functional delivery experience. I'm open to full-time international opportunities, relocation, remote work and visa sponsorship.
