Uai, from Minas Gerais to the world

It's a pleasure to meet you, uai!

When I was studying computer engineering, the most common mindset was build any site or app to make the code compile and work. At that time, little was said about the importance of usability.

I did my thesis about long-term financing and developed an app focusing on teaching people about it. To validate the App, I needed to do in-depth interviews and usability testing with 14 people, and the result of all of this was me jumping head first into UX.

In 2018, I moved to another city and got my first job as a front-end developer, but my curiosity about UX/UI design only grew.  I found an opportunity and applied. Then started my career as UX & UI Designer.

That's the reason I have chosen to create user-centric, delightful systems and apps.  When I’m not designing, you can find me watching tv, reading, traveling, or annoying my dog.

Let’s grab a coffee.

Testimonials

People who trusted my work

“I had the pleasure to work with Tamires for almost two years in a high-profile project for Brazil's biggest public bank. She is extremely dedicated and capable of connecting with the users' needs.

Being such a talented UX professional, she focus on results and she was never shy to think about ways to push the boundaries to make our product better.

Also, on a personal level, she is very easy-going, always in love with her work and a great listener. Feel free to reach out to me, if you need more information.”

Carol

Carol was the Product Owner at Unisys

"Tamires is a natural talent in UX. Her incredible creative capacity, combined with empathy and the ability to understand complex scenarios from different perspectives, makes her highly capable of performing all the different functions related to user experience.

As natural talents need constant development, her relentless desire to learn, discipline, and engagement motivate her to intelligently seek out and face the challenges that come her way (and she overcomes many during our successful journey together in UX!)."

Tamires is always open to feedback and turns it into growth remarkably quickly. She's a supportive teammate, a fast learner, and someone who truly gives her best. I’m grateful to have had the opportunity to work with her."

Sara Youssry

Product Design Lead at Insense

“Tamires is one of the most dedicated, collaborative, and feedback-oriented professionals I know. Her desire to grow and do better, along with her humility to listen and learn, is only surpassed by her immense talent for leading immersive UX Design processes and delivering strong results in the projects she is involved in.

We worked together at Stefanini, both in person and remotely. In addition to planning the entire process and working with clients with great professionalism, she worked hard to ensure deadlines were met and always brought human connection and empathy to the team. She is an excellent professional whom I highly recommend.”

She is also very funny, and her laughter brings positive energy to the environment and makes everything feel lighter. I’m so glad I had the pleasure of working with her, and even today, I feel inspired by her."
