I'm a DevOps engineer who builds things that work reliably. After several years managing IT teams, I dove deep into the technical side — automating, monitoring, and scaling systems from scratch.

About Me
Pavel Khaustov
DevOps Engineer
DevOps engineer passionate about building reliable, automated infrastructure. After years leading IT teams as CIO, I pivoted to hands-on engineering — containerizing, scaling, and securing systems myself.

Philosophy
"Automate everything that can be automated. Monitor everything that runs. Document everything you build."
Fun fact
I run a full K3s cluster on bare metal at home — purely to break things and learn how to fix them.
~/Autonomous AI & Automations
Autonomous AI & Automations
Real AI solutions that generate revenue and automate workflows.
E-commerce AI Agent
Task
Automate sales with an LLM integrated directly into the backend.
Solution
Engineered an autonomous agent that doesn't just chat, but closes deals. It processes natural language, checks inventory via API, and generates $3,000–$4,000 in passive revenue monthly.
LLM-Powered QA Pipeline
Task
Eliminate manual call reviews in the sales department.
Solution
Built an automated pipeline that transcribes audio, analyzes dialogue context using LLMs, and outputs structured performance metrics and analytics.

~/Live Infrastructure
Live Infrastructure
Real systems, running live. Everything you see below is pulling actual data.
Kubernetes Cluster
Task
Run containerized workloads with zero-downtime deployments.
Solution
Self-hosted K3s on bare metal, deployed via GitLab CI + Helm. Namespace-isolated, with RBAC and auto-scaling.
Live pods from devops-portfolio namespace:
GitLab CI/CD Pipeline
Task
Fully automated build, scan, and deploy on every git push.
Solution
5-stage pipeline: test → build → Trivy scan → staging → manual prod gate. ChatOps bot sends Telegram approval request.
Monitoring Stack
Task
Full observability across the cluster.
Solution
Prometheus Operator scrapes metrics, Grafana visualizes, Loki + Promtail aggregates logs.
Disaster Recovery
Task
Automated backups with point-in-time recovery.
Solution
Velero snapshots entire namespaces weekly to Cloudflare R2 (S3-compatible). Full cluster restore in under 15 minutes.
