Rework portfolio around Linux operations, Zabbix monitoring, migration validation, and ELK/Grafana log observability.

Add AAP-style LVM resize workflow, Zabbix server/proxy/agent automation assets, Linux/AIX monitoring templates, and updated validation CI.

# CV-Aligned Linux / Unix Infrastructure Portfolio
This repository maps my Linux/Unix infrastructure experience into practical, reviewable projects: operations automation, monitoring, incident response, migration validation, and log observability. It is intentionally grounded in the kind of work described in my CV: large Linux/Unix estates, Zabbix monitoring, storage and migration work, provisioning, patching, troubleshooting, and operational evidence.
The repository also leaves room for DevOps side labs, but the main section is professional infrastructure work rather than cloud-native/platform fantasy.
## What To Review First
| Order | Project | CV relevance | Technologies | Validation |
| --- | --- | --- | --- | --- |
| 1 | [Linux Operations Automation](professional-infra/linux-operations-automation/) | Linux server deployment, patching, hardening, LVM resize operations, AAP-style automation | Ansible, Bash, Docker Compose | `cd professional-infra/linux-operations-automation && make test` |
| 2 | [Zabbix Monitoring + Incident Response](professional-infra/zabbix-monitoring-incident-response/) | Zabbix maintenance, proxy topology, active/passive checks, Linux/AIX OS monitoring | Ansible, Zabbix templates, YAML | `cd professional-infra/zabbix-monitoring-incident-response && make test` |
| 3 | [Migration Validation Framework](professional-infra/migration-validation-framework/) | Pre/post migration validation, reporting, drift detection, evidence generation | Python, JSON, HTML | `cd professional-infra/migration-validation-framework && make test && make demo` |
| 4 | [Log Observability ELK/Grafana](professional-infra/log-observability-elk-grafana/) | Log ingestion, incident evidence, environment observability | Docker, ELK, Grafana, Filebeat | `cd professional-infra/log-observability-elk-grafana && make test` |
## CV Skills To Repo Map
- **Linux/Unix operations:** Linux Operations Automation, LVM resize workflow, patching, hardening, service checks.
- **Automation:** Ansible playbooks/roles, Bash simulation scripts, Python validation tooling.
- **Monitoring:** Zabbix project for OS checks and proxy operations; ELK/Grafana project for log monitoring.
- **Migration work:** Migration Validation Framework for before/after evidence and drift reports.
- **Incident response:** Zabbix runbooks, ELK incident simulation, failure simulation examples.
- **DevOps practices:** lightweight CI, Git workflows, repeatable `make test` targets, containerized lab components.
## Professional Infrastructure Projects
The `professional-infra/` directory contains the projects that should be read as direct support for the CV. Each project includes a reviewer-focused README, validation command, examples, and interview talking points.
## DevOps Side Labs
Future side projects can live under `devops-labs/` when they are ready. Good candidates are K3s, CI/CD workflow demos, cloud experiments, Wazuh, or other after-hours labs. Empty placeholder project directories are intentionally avoided.
