Bereke Auto CRM

A fleet-rental company's CRM, inherited after its developer vanished, with the source only on the server. Kaspi invoices to drivers had stopped arriving, and before that some went to drivers whose contracts were already closed.

Reading the system through its own API: the Kaspi session died because someone logged into the cashier's account from another device, and closed contracts kept billing because the driver fell back to a per-driver daily amount that was never reset. Private client work, so no screenshots.
