01 / About me

Full-cycle engineering —
from requirements to reliable production.

I work across the entire enterprise application delivery lifecycle: understanding business requirements and technical specifications, analyzing data flows, planning ETL workflows and reporting solutions, and preparing the underlying application platforms.

My hands-on work has covered configuration and development, source and repository changes, data validation and testing, pre-production deployments, production releases, post-deployment verification, monitoring, incident and problem investigation, and controlled data reprocessing when needed.

I have also configured clustered platforms and high availability, contributed to disaster recovery plans and failover tests, and produced application runbooks, operational guidance and knowledge-transfer materials. This background supports production reliability and Site Reliability Engineering (SRE) practices.

Within containerized application delivery I have worked with Mirantis Kubernetes Engine, Kubernetes YAML and Secrets, and Bamboo/Artifactory release workflows. My focus here is hands-on production systems, not unverified public-cloud experience.
