Signly is a full-stack digital document signing platform that allows users to upload PDF documents, create custom signatures, place signatures through a drag-and-drop interface, and securely finalize documents.

The platform also includes audit tracking, role-based authentication, and document management features, making it a strong case study in building a trust-focused workflow around secure document handling.

The core product experience includes JWT-based authentication, PDF handling, custom signature creation, drag-and-drop signature placement, audit history tracking, secure signing workflows, and role-based access control.

A responsive interface was built around usability and document management, with an emphasis on keeping critical actions clear while supporting a more complex end-to-end signing flow.

Signly was built with React and TypeScript on the frontend, supported by Tailwind CSS for the interface layer, and powered by Node.js, Express, and MongoDB on the backend.

JWT authentication, Axios-based API communication, and deployment on Vercel and Render helped shape the project into a practical full-stack application with clear production-style boundaries.

Building Signly gave me hands-on experience with file handling, PDF workflows, authentication systems, secure document management, and audit tracking in a product where trust and traceability matter.

It also strengthened my understanding of scalable full-stack architecture and taught me how to make technically complex workflows feel simpler through careful interface design.
