Infrastructure / AI Automation Engineer / DevOps
Reliable infrastructure with automation built in.
Senior Linux infrastructure and DevOps engineer with 15+ years across production systems, virtualization, observability, backup strategy, and self-hosted AI workflow automation. Focused on resilient operations, clean recovery paths, and pragmatic automation.
Profile
Production ownership across infrastructure, observability, and AI automation.
Based in Koszalin, Poland, I work across Linux operations, multi-region service delivery, monitoring stacks, CI/CD, backup and disaster recovery, security hardening, and experimental AI systems. I have operated as the sole DevOps/SRE owner in multi-product environments and prefer systems that are measurable, repairable, and easy to reason about under pressure.
Expertise
Hands-on capabilities across the operational stack.
Linux infrastructure
RHEL, Fedora, CentOS, Debian, Ubuntu, and FreeBSD basics across long-lived production environments.
Virtualization and containers
Proxmox with KVM and LXC, Dockerized services, backup flows, and Kubernetes proof-of-concept work.
Monitoring and logging
Zabbix, Nagios, Graylog, Wazuh, Grafana, and ELK-based visibility for incidents, trends, and control.
Networking and edge services
VPN, VLAN, firewalls, DNS, load balancing, mail authentication, and operational troubleshooting.
CI/CD and automation
Jenkins pipelines, deployment flows, Bash scripting, Node.js utilities, and lightweight automation tooling.
AI workflow systems
n8n orchestration, OpenAI API integration, self-hosted LLM experiments, and agent-style workflow design.
Experience
Recent roles and operating environments.
DevOps / Infrastructure / AI Automation Engineer
Own infrastructure across six dedicated OVHcloud servers, Proxmox nodes and clusters, custom backup storage, internal VPN, Dockerized services, and multi-region workloads spanning Europe and Canada.
- Managed roughly 50 production services with 24/7 on-call responsibility.
- Built centralized monitoring with Zabbix, logging with Graylog, and security monitoring with Wazuh.
- Handled bare-metal recovery, DNS and email authentication, DDoS mitigation, and PCI-related validation work.
AI Automation & Infrastructure Projects
Built self-hosted automation environments around n8n, OpenAI API integrations, local LLM infrastructure, and multi-step prompt orchestration for practical recommendation, content, and aggregation workflows.
- Integrated OpenAI through built-in tooling and custom Node.js proxy layers.
- Deployed and tuned local model environments including llama.cpp-based stacks.
- Explored multi-agent and cybersecurity-oriented AI automation patterns.
Self-employed Product Project
Built and released a mobile product with Flutter frontend, Dockerized Node.js backend, MySQL, Firebase and Google OAuth integrations, push notifications, and deployment owned end to end.
- Delivered the app to Google Play with full-cycle ownership from architecture to release.
- Hosted backend services on VPS infrastructure with minimal CI/CD automation.
CloudOps / SysOps Engineer
Provided AWS-focused L1 production support covering EC2, RDS, S3, IAM, backup and restore procedures, incident analysis, and documented infrastructure changes.
Projects
What I build and optimize now.
Infrastructure
Multi-region service operations
Production systems spanning EU and North America with backup strategy, observability, incident response, and recovery planning built into the platform.
AI Automation
Self-hosted workflow orchestration
Automation pipelines for recommendations, news aggregation, content flows, and controlled agent access using n8n, local models, and API integrations.
Security
Operational hardening
WAF and DDoS mitigation, mail authentication, malware cleanup, monitoring controls, and practical defensive improvements for exposed services.
Product Delivery
Application deployment ownership
Shipping mobile and backend products with Docker, MySQL, Firebase integration, and lightweight release automation from a single technical owner.
