This looks like a great fit, I will secure the web app, auth hardening, TOTP two-factor, encrypted data transactions, admin access controls, and AWS monitoring. For 2FA, I will implement TOTP over SMS, authenticator apps generate codes locally with no SIM-swap vulnerability and no per-message cost as user volume grows. SMS is the most common attack vector on otherwise secure auth systems. Questions: 1) Is the app deployed on AWS already or still local? 2) Which backend framework, Node, Django, Laravel? Looking forward to your response. Best regards, Kamran
