In production

Built the payment gateway behind a SoftPOS platform's bank connection — key injection and rotation, DUKPT key derivation migrated across generations (legacy TDES DUKPT through to AES DUKPT), KSN/BDK provisioning, ISO 8583 message assembly, and the acquiring-bank interface itself. Every device's key material gets rotated and re-derived without interrupting a single live transaction.
