Assine Online | Platform Redesign and Design System Creation
Mission
Enhance the user experience and usability of Assine Online, a digital document signing platform with full legal validity.
The goal was to make the document submission flow clearer, align the interface with the brand’s visual identity, and establish a foundation for future scalability and product evolution.
My Contribution
As the Product Designer responsible for the platform redesign, I led the process from diagnosing usability issues to delivering a new interface, usability tests, and the foundation of the Assine Online Design System.
My main contributions included:
Redesigning the document submission flow for clarity and efficiency.
Conducting benchmark research on digital signature platforms.
Creating the initial Design System with documented components and styles.
Delivering high-fidelity prototypes for validation.
Structuring a phased transition plan to minimize user disruption.
Results
A simpler and more intuitive interface, focused on the document submission journey.
Clear visualization of key metrics and recent user activity.
Positive reception of the new design and visual consistency.
Planning and design of the Assine Online mobile app, enabling document signing on the go.
A foundation for long-term scalability through the Design System.

Process
The Assine Online platform had been developed externally before the company established its internal product team.
This led to delays, usability flaws, and inconsistencies between the platform and brand identity.
My first task was to identify the main usability and visual issues that could be solved in the short term while defining a strategy for long-term improvement.
Key improvement areas:
Confusing document submission flow.
Unclear dashboard metrics and feedback.
Visual inconsistency with the brand identity.
Lack of a responsive version.
Through benchmarking, I analyzed leading e-signature platforms and identified several best practices:
Highlight the document upload area as the main focus.
Offer ready-to-use templates to streamline the signing process.
Simplify instructions and actions for better user guidance.
Plan a mobile app dedicated to sending and signing documents in a future phase.
Outcome
Before implementing major design changes, I worked with the development team to understand technical constraints and production impact.
We concluded that a complete rebuild of the platform would be more effective than patching the existing version.
The redesigned experience prioritized:
Clear information hierarchy on the homepage.
Visual feedback for critical actions, such as pending signatures.
Standardized visual components for consistency and scalability.
During usability testing with internal teams, several insights emerged:
Users found the new document submission flow more intuitive.
They clearly understood the metrics and activity feedback displayed.
The visual identity and tone were well received.
Some users requested quick resend options using drafts or past submissions.
Pain points identified:
The drastic interface change caused initial confusion for returning users.
The new contact/group registration flow required additional explanation.
The plan usage display introduced complexity, as the product had previously been free.
To minimize friction, I proposed a four-phase rollout plan:
Update colors and typography to align with brand identity.
Refresh the website to prepare users for the new interface.
Reorganize content to match the upcoming design direction.
Launch redesigned components and interactions.
Design System and Mobile App
With the redesign validated, I began documenting the Assine Online Design System, defining component libraries, interaction rules, and visual patterns — ensuring consistency and efficiency across the product.
As a final contribution, I designed the Assine Online mobile app, focused exclusively on document upload and digital signing.
The app’s design was based on the Design System and guided by insights from earlier user research and benchmarking.
Key Learnings
Large-scale redesigns should be rolled out in phases to preserve user familiarity and adoption.
Even small usability tests provide critical feedback for refining major changes.
Visual and brand consistency directly impacts user trust and perceived product quality.
