Introduction:
Zeki Expert Solutions collaborated with a productivity tools provider to develop Advanced PDF Viewer, a cloud-integrated, feature-rich PDF utility built on the MERN stack. The platform supports advanced PDF editing, annotation, OCR, digital signatures, and enterprise-grade security, delivering a seamless document handling experience for users and teams across industries.
Why They Chose Us & Our Goals
The client chose Zeki Expert Solutions for our full-stack expertise and experience with cloud-native tools. Their goal was to build a secure, scalable PDF management system to replace scattered offline tools and enable smarter document collaboration, editing, and signing, within a single, intuitive platform.
Today’s fast-paced work environments demand smart, secure, and collaborative document workflows. Advanced PDF Viewer was created to meet that demand with precision, speed, and flexibility.
Fragmented Tools to Unified Solution
Before working with us, the client relied on multiple disjointed tools for PDF editing, signing, and sharing. This caused inefficiencies and security risks. We proposed a single, browser-based solution with robust editing, annotation, and OCR capabilities.
Full-Stack Engineering with Smart Features
Using MongoDB, Express, React, and Node.js, we created a performant system with PDF.js for rendering and Tesseract.js for OCR. Key features included real-time annotations, digital signature embedding, and customizable permission settings.
Cloud Integration & Security Controls
Documents are encrypted and stored on AWS S3 with access control. We integrated role-based permissions and audit logs to help teams track changes and ensure regulatory compliance.
