Automation with Ansible: idempotent playbooks, roles and secrets in Vault

I configure servers and deploy applications with Ansible so that infrastructure preparation stops being a manual ritual and becomes a repeatable process without your constant involvement. I write idempotent playbooks and careful reusable roles, maintain inventory for each environment and store secrets in Ansible Vault. You describe the desired state once, and I turn it into code that gives the same result on the first run and on the hundredth — whether it's a single VPS or an entire fleet of machines.

All work is built around predictability. Each role is parameterized: staging, testing and production use the same logic and differ only in variables. I separate concerns into tasks, handlers and templates, protect changes with checks and tags, run everything in check mode before it touches a live host. No unexpected restarts, no half-applied configuration, no drift between servers that should have remained identical. When something changes, you update a variable, not dozens of machines by hand.

I can start from your current configuration or build a structure from scratch and hand over a documented repository that your team can manage without me.
