"After one year and five months of work, Dias is the sole UI Designer (Delivery) responsible for the development of high-precision projects such as the Estácio de Sá app, whose model serves as the foundation for all the applications we work on. He collaborates directly with the board of directors, coordinators, and the web development team to help prioritize needs; in this way, we resolve conflicts and establish content criteria within a system that only highly qualified designers are capable of contributing to. It was a great pleasure!"

"After hiring him on Paulista Avenue, I saw Rafael excel in a self-service checkout stations project that was already underway. He demonstrated remarkable professional growth, refining and accelerating its implementation in under four months, aligning with Brazil's concept catalog.

Tied to interfaces and technology, the program became vital for users and the company. Rafa developed the full product design, rolled out across all Decathlon stores in Brazil in 2021 and still operational today.

The project succeeded fully, earning positive customer recognition. He is a highly valuable professional in his field, dedicated and effective. Thank you, Rafa! 😊”

"During the campaign of candidate Paulo Skaf for governor, there were several large teams working with us, all hired by the candidate, to which Rafael was able to contribute his excellent academic background and experience in visual design. In work processes such as political campaigns, both the company and the client require the utmost attention to detail in order to stand out and achieve success. Rafa was required to work full-time for eight hours a day, but it was not uncommon for us to exceed ten hours on some days or even work into the night, as we were always keeping an eye on competitors and news in order to produce outstanding creative materials (a political campaign is not for everyone).

Rafael’s professionalism, diligence, and attention to detail and specific requirements were always evident in his work throughout the campaign. Indeed, I do not hesitate to say that his technical expertise, academic background in Visual Design, and professional experience were decisive for the success of our projects. In fact, some of these works are featured in the online portfolio of Tikao Comunicação."

"Rafael is tireless in his personal and professional development. During the time we worked together, it was clear that he is an outstanding professional in the market. His communication skills and sensitivity in creating deep perceptions through design provide him with a solid foundation to tackle increasingly greater challenges. He is dynamic, focused, innovative, and an excellent colleague!"
