Customer Self-Service & Secure Document Vault
Engineered an encrypted customer portal that unified digital document uploads, e-signatures, audit trail logs, and billing history, cutting support tickets by 54%.
1. Challenge
A financial and corporate services advisory firm handled over 3,000 monthly client inquiries via unencrypted email attachments. Clients frequently lost track of signed documents, support staff spent half their week manually tracking invoices, and security compliance risks mounted.
2. Solution & Technical Architecture
Norvi Infotech India developed a high-security customer web portal with:
- Zero-Knowledge S3 File Vault: End-to-end encryption with pre-signed upload URLs and server-side KMS encryption.
- Multi-Factor Authentication (MFA): TOTP authenticator app support and email backup verification codes.
- Real-Time Ticket & Document Status: WebSocket-powered notification banners keeping clients informed of file review milestones.
