Claro

Claro Brazil is a telecommunications operator offering mobile, satellite TV, fixed-line, and broadband services across Brazil.

Role

Worked as the sole Product Designer in an Agile team of 3 developers, a product owner, scrum master, quality engineer, and product manager. Led design direction, ideation, and cross-functional collaboration.

Design Process

My approach followed a structured UX process:

Empathize: Stakeholder interviews, journey mapping, competitor analysis

Define: Problem statements, personas, user journeys

Ideate: Information architecture, user flows

Design: High-fidelity prototypes, visual design

Test: Usability testing, Google Analytics insights, iterative improvements

Tools: Figma, Miro, Microsoft Office

Problem

Developed and implemented an alternative login and sign-up experience for Claro’s mobile app, improving accessibility and reducing friction for users. The new flow allowed login via mobile number with a verification code, in addition to email/password.

Solutions

Introduced dual login options: email/password and mobile number with verification code.

Designed a flexible system allowing users to select their preferred method in app settings.

Maintained component consistency by leveraging existing design system standards.

Challenges

Iterated multiple design concepts due to development constraints and tight timelines.

Results

Increased active clients by 70.5K in the first month.

Boosted app downloads and improved onboarding experience.

Outcome

Reinforced the value of prototyping, validating new concepts, and keeping designs aligned with user needs and technical feasibility.
