Infrastructure
Cloud, hybrid systems, identity, endpoints, virtualization, networking, and the operational discipline needed to keep them useful.
Infrastructure / Operations / Automation
Denis Tolochko
IT Systems Operations Engineer
I build reliable infrastructure, cloud operations, and automation systems for teams that need technology to stay calm under pressure.
My work sits where operations, security, and delivery meet: improving existing environments, removing repetitive work, and leaving teams with systems they can understand, maintain, and trust.
I’m open to new opportunities, practical collaborations, and candid feedback. I do my best to stay attentive to these channels, so if you see a useful connection or have an idea worth exploring, please get in touch.
Current role
Turning cloud chaos into predictable systems.
IT Systems Operations Engineer focused on infrastructure as code, AWS and Azure operations, DevOps workflows, security-minded administration, and practical automation. The goal is simple: make deployments boring and systems trustworthy.
Automation
Scripts, repeatable workflows, infrastructure-as-code patterns, monitoring, and small tools that remove recurring manual work.
Risk Signals
Security, reliability, backup readiness, incident patterns, dependency health, and the weak signals that become outages if ignored.
Selected paths
Experience across support, systems, and transitions.
Notes and research
Writing about infrastructure, operations, and the work behind the work.
Short technical notes, longer career reflections, and practical documentation from systems work.
