Project Overview

An enterprise-grade, end-to-end encrypted cloud storage platform with team collaboration tools, file versioning, granular role-based access control, and real-time sync — deployed on AWS for global performance.

The Challenge

The client needed a secure alternative to consumer cloud storage for sensitive business documents, with strict access controls and cross-team collaboration — without sacrificing security or auditability.

Our Solution

Built on AWS S3 with client-side AES-256 encryption before upload. Node.js backend handles versioning, access control lists, sharing links with expiry, and real-time activity feeds.

Results Achieved

Over 1TB of sensitive data stored with 100% uptime since launch. Transfer speeds reach 10Gbps on enterprise plans, and the company passed their ISO 27001 audit using the platform's built-in audit logs.

What We Built

Key Features Delivered

Every feature built to solve a specific problem and drive measurable outcomes.

Client-Side Encryption

Files are encrypted before leaving the device — the server never sees plaintext data.

File Versioning

Every file change is versioned. Restore any previous version with one click, up to 12 months back.

Role-Based Access

Granular permissions — owner, editor, viewer, commenter — per file, folder, or project workspace.

Collaboration Tools

Real-time comments, @mentions, and activity feeds keep teams aligned without leaving the platform.

Secure Sharing Links

Password-protected, expiry-limited sharing links for external collaboration without creating accounts.

Audit Logs

Complete audit trail of every access, download, and change — timestamped and user-attributed.
