Legal Document Management & E-Signature Platform

A legal document platform needed to cover the full life of a document: creating it, assigning it to signers, and running a structured, multi-step signing process where every signer completes only the fields that belong to them, in the right order.

I built frontend features across document creation, signer management, assignment workflows and the signing experience, along with reusable components shared across the editing, signer management, Smart Field and signing modules.

• Embedded TinyMCE as the document editor so content could be imported, pasted or typed manually, without building a custom editor.
• Used regex-based mapping to create dynamic Smart Fields inside the document and tie each one to an individual signer.
• Modeled signing as a sequential workflow: field visibility and completion state are derived from the signing order, so each signer sees only their assigned fields.
• Built digital signature capture on HTML5 Canvas and kept it as a reusable component.

A single, consistent workflow from drafting to final signature, with signer isolation enforced in the UI and reusable building blocks shared across every module of the platform.
