Fishing Trips

Freelancer - UI Designer

The app centralized and simplified the content and interactions of the engaged professional fishing community.

It features documenting and sharing fishing trips in technical details, easy search for accommodations and specialized fishing stores, and social features such as chat and posts.

As a freelancer, I designed the final UI of the app and the company’s backoffice system, including an advanced token and component library.

Cosmos Design System

Hotmart - Product Designer

A designer mentioned in an interview "I joined the company with three deliverables to complete in a short time, and if it weren't for Cosmos, I wouldn't have been able to accomplish them".

In the beginning, the library had several critical issues, product teams weren't engaged with Cosmos, there was no design documentation, nor any process, also a lot of work on governance, rollout, and workshops to skill up other teams.

After continuously diagnosing Cosmos through research, we've worked hard to improve these aspects and I could see that the design system had reached a decent level of maturity, accelerating development and increasing product quality.

About the process

Footwear company *

Consultant - UI Designer

The product was designed to provide comfort to the company's VIP customers, allowing them to receive, try on, and purchase shoes in their homes, all managed with the app.

It has virtual storefront, shopping cart, and payment capabilities, providing a fast and personalized shopping experience using customer registration data.

The MVP was born out of a design sprint, involving dynamics with strategic stakeholders for business definitions, service flow, interface design, and usability testing. My role focused on the product's UI.

Lumen Design System

Pipefy - Product Designer

I enhanced several soft and hard skills and helped my teammates expand their technical skills and increase their productivity, independence and engagement.

I had the opportunity to lead the design system team, facing challenges such as engaging product teams with Lumen, streamlining processes, dealing with various technical issues in a legacy version, and tidying up the design system's foundation.

We conducted numerous researches and workshops to diagnose and create an efficient design system. After a period of negotiation, we began building a library of high-quality tokens and components, along with documentation, strategically supporting important ongoing projects, ensuring a positive and immediate impact.

The company is recognized for embracing truck drivers, offering a range of benefits that go beyond the main product - fuel - and the application is designed to enrich this experience by centralizing freight offers, digital wallets, legal and financial support via chat, among other features, thus facilitating the daily lives of this audience.

My role focused on UI and I also assisted in interviews with personas, business definitions, and usability testing, along with a UX researcher.
