# Andaç Kartal — independent IT consulting

> Ahmet Andaç Kartal, an independent IT consultant based in Istanbul, Türkiye.
> He scopes infrastructure work and stays accountable for it; AI agents carry
> out the execution over the same interfaces administrators already use —
> WinRM, SSH and vendor APIs — and every step is written to an auditable log.

The site is two hand-written pages, English at / and Turkish at /tr/. There is
no blog and no feed; the evidence on the page is measured infrastructure data,
not writing.

## What he does

- Windows and Linux fleet operations: patching, hardening, configuration drift
- Virtualisation, migrations and version upgrades across vSphere, Proxmox and
  cloud KVM, with a tested rollback path written before the first change
- Runbook automation: manual monthly procedures become procedures that run
  themselves and report what they did
- Line-of-business software where nothing off the shelf fits: e-invoicing
  against an integrator's SOAP interface, shop-floor dashboards, file-integrity
  monitoring
- Identity and access: Active Directory, LDAP-backed sign-in, password
  management, agentless Windows administration over a private mesh
- Audit evidence generated as the work happens

## What he will not do

- Run a destructive step without approval — every time, not just the first
- Let an agent improvise; an out-of-scope condition halts the run and reports it
- Ask for write access to a production database; read-only diagnosis is default
- Bill for out-of-scope work that was not put in writing first
- Promise "full compliance" — he says which half is his and which is the vendor's
- Put hardware or licence costs through his invoice
- Sell hours; the engagement buys a defined outcome and an agreed response time

## Scale currently under management (measured 26 August 2026)

- 4 hypervisor platforms: VMware vSphere 7, Proxmox VE 8, Hetzner Cloud,
  Oracle Cloud (ARM64)
- 5 physical hosts, 128 cores / 256 threads, ~1.37 TB RAM
- 99 virtual machines, 19 system containers, 88 application containers
- ~50 VMware Horizon virtual desktops, ~31 concurrent sessions
- 29-node WireGuard mesh across 3 countries, x86_64 and ARM64
- 22 years of systems and infrastructure work in manufacturing

## Engagement

- A monthly retainer against a written scope; out-of-scope work is quoted
  separately before it runs
- A defined first step is available: a two-week, read-only infrastructure
  review producing a written assessment and a prioritised fix list
- Thirty days' notice either direction; documentation stays with the client
- Invoiced from a Turkish sole proprietorship, VAT added on top
- Correspondence in English or Turkish
