Remembering Atatürk with Respect and Longing

Mustafa Kemal Atatürk, founder of the Republic of Turkey, passed away at 09:05 on 10 November 1938 at Dolmabahçe Palace in Istanbul. Every year at this time the whole country stands in silence.

Keeping alive the Republic he entrusted to us is a duty we all share.

My humble body will one day turn to dust, but the Republic of Turkey will stand forever.Mustafa Kemal Atatürk

Overview

Free work order tracking for phone, computer and appliance repair shops. It has check-in receipts, quote approval, parts stock, payments and a status page customers follow on their phone, and shops can connect an AI assistant such as Claude over MCP to ask about their work orders. Turkish and English.

01 · Problem

Small repair shops run on paper tickets. Customers keep calling to ask about their device, and existing software charges per user and is mostly English-only.

02 · Solution

A multi-tenant web app built on Clean Architecture. It has a check-in form that adapts to the device type, QR receipts, a status flow, stock and payments. Customers approve quotes from a login-free tracking link and get email and browser notifications. With its MCP server, a shop can connect an assistant such as Claude over OAuth 2.1 and ask "which devices are ready for pickup?"; the assistant can change a work order's status, while delete, payment and pricing tools are left out on purpose.

03 · Outcome

Live and free. Covered by 744 automated tests (real PostgreSQL, CSRF on every POST, tenant isolation). The assistant's token carries no permissions: shop and role are read from the database on every request, so a revoked connection stops at the next call. Strict CSP, encrypted device passcodes and a fast deployment on my own server behind Caddy.
