 About me

As a Data Scientist and Engineer, I specialize in transforming complex data into tangible business outcomes, particularly for the retail and consumer packaged goods sectors.

My expertise lies in deploying advanced analytics algorithms, deep learning solutions, and machine learning approaches.


The passion for exploring the convergence of graphics technology platforms and analytics solutions, particularly in areas such as gaming and the metaverse, has been a driving force in my career, as in the coming years this unique intersection will offer numerous innovative solutions that can contribute effectively to a tangible impact.

My journey in this field was initiated some years ago with a self-taught venture into Unity programming, which not only laid the foundation for my technical background but also sparked this deep interest.

 Personal life & Hobbies

I’m a person who loves to read about issues related to the gaming industry, especially in companies such as Activision Blizzard, Ubisoft, Bethesda, Xbox Studios, Supercell, among others; also in matters of marketing and applicability of Data Analysis in development, design, research and postproduction – That’s why two of my main appeals are Applied Data Science and Game Development.

Among other personal hobbies, I like playing video games and practicing outdoor sports like trail running. And a fun fact — I live with a golden Holland Lop named Jacka.
