Learning Plataform

A responsive learning platform and mobile app developed for an edtech company

Overview

Every year, about 5.8 million Brazilian students take the ENEM (National High School Exam) and other similar tests to gain admission to college. To support their preparation, the company offers an online learning platform.

The goal of this project was to improve the platform’s interface, making it more intuitive, user-friendly, and responsive. We also worked to ensure accessibility on both the Apple App Store and Google Play Store, allowing students to study anytime and anywhere.

My role

I worked on this project from 2019 to 2021, starting with hands-on design work and later moving into a leadership role. My responsibilities included leading the discovery and ideation phases, improving the platform interface, and defining a new application design. I also initiated documentation for the company’s design system.

As the project evolved, I transitioned to guiding and mentoring other designers, ensuring a consistent, high-quality experience for students across devices.

Discovery

The development of the new platform unfolded in several stages.


To understand the project’s context, I immersed myself in the product, the solution it aimed to offer, and the students’ needs. The challenge was to enhance the platform without disrupting their established study routines.

User Persona

Ana, 22 year-old student - São Paulo.

Ana is applying to a public university for the second time, pursuing her dream of becoming a cardiologist. She is committed to her studies and enjoys spending her free time with family, scrolling through social media, and watching TV.

Top Goals

• Begin higher education
• Start a career in medicine
• Achieve financial independence

Frustations

• High cost of preparatory courses for medicine
• Commuting long distances to attend classes
• Falling behind when a class is missed

Defining

One of the main challenges students faced was keeping track of their weekly class schedules and related materials. To address this, we developed the Study Plan feature, giving them a clear, organized view of upcoming lessons and resources. 

I also researched competing solutions and interviewed experienced team members to gather insights from their direct interactions with students. These findings informed both immediate feature improvements and a roadmap for future enhancements.

Developing

I created user flows in wireframes, organizing them by core features such as Mock Test, Subjects, Essay, and Study Plan. These flows were validated in review sessions with stakeholders, where I walked them through each step and collected feedback.


The insights gathered informed design refinements and guided priorities for the following sprints.

Delivering

With the user flows approved, I moved into crafting high-fidelity designs for each feature.


For complex interactions, I built interactive prototypes to run usability tests, ensuring a smooth and intuitive experience before handoff to developers.

Prototyping

I developed interactive prototypes to validate design decisions and refine the user experience before implementation.

 

These prototypes were used for usability testing, enabling the team to identify improvements early and ensure a smooth development process.

Design System

To support collaboration across teams and maintain a unified brand identity for the new platform, I created the first version of the Design System.

 

This resource documented reusable components, visual guidelines, and interaction patterns, ensuring consistency while improving the team’s efficiency. I continued to evolve and maintain it, adapting to new features and product needs over time.

Results
Prototyting time reduced.

By implementing the Design System and streamlining workflows, the team reduced delivery time by almost 32%.

 

This included incorporating developer feedback early in the process to avoid rework

Daily active users increased

Within the first quarter after launch, the number of students watching at least one class per day from their study plan increased by about 24%.

Time spent on the apps doubled

The average session length on both the App Store and Play Store grew by approximately 101% in the first year, indicating higher engagement and retention.
