File management system and electronic signature service
All About
eSign is a mobile digital signature application that enables users to manage, edit, and sign documents directly from their smartphones. The product combines electronic signing capabilities with built-in file management, allowing users to upload documents, organize files, rename them, and perform secure signing workflows without relying on desktop tools.
Our team carried out a full redevelopment of the Android client from scratch, replacing an existing legacy application ahead of a planned public release. We implemented a new UI design, extended core signing functionality to allow users to edit and sign documents entirely within the app, and built a robust file management system covering file upload, organization, renaming, and deletion. Following the launch, we continued with long-term development and maintenance, ensuring stability, feature growth, and Play Store compliance. This project highlights our expertise in rebuilding production apps, safely migrating users to a new version, and delivering feature-rich mobile solutions that meet real business and legal workflows.
