At GreatWorks Technologies, we offer a secure and legally compliant Digital Signature App designed to simplify the way businesses and professionals manage document approvals. Whether you're onboarding clients, signing contracts, or verifying compliance documents, our app streamlines the entire signing process with ease and reliability.
The platform supports real-time digital signatures on documents like PDFs and Word files, offering features like drag-and-drop signature fields, initials, date fields, and custom tags. Every signature action is backed by an audit trail, recording user actions, time stamps, IP addresses, and authentication methods to ensure full transparency and legal validity. We support biometric authentication, OTP verification, and email verification to secure every transaction.
Users can upload, share, and request signatures via the app or web portal. With cloud storage integration (Google Drive, Dropbox, AWS S3), signed documents are automatically saved for future access. The platform supports multiple roles (sender, signer, admin), allowing businesses to define workflows, set reminders, and track document statuses. Notifications keep all parties informed on pending and completed tasks, while automatic version control helps manage document revisions.
Built using React for a responsive web interface and Flutter for Android and iOS apps, the backend is powered by Node.js or Laravel. Real-time communication is handled through WebSocket, while JWT authentication secures user sessions. We use PDF.js and Docusign/eIDAS API libraries to ensure legal compliance across major global regulations including eIDAS, ESIGN, and UETA.
