ui designer | illustrator
Chicago, IL.


Hi, my name is Carlos Santiago and I am a designer from Puerto Rico based in Chicago, Illinois. For the last three years, my work revolves around digital and physical products ranging from User Experience, User Interface for desktop and mobile, prototypes and illustrations, both hand-drawn and vector-based.

I’ve had the opportunity to work for Critical Mass, Sony Music | Columbia Records, Sears Holdings, Abelson-Taylor, CAHG, Frequency 540 as well as August Jackson, just to name a few.

I graduated from Robert Morris University in 2014 with a Master’s of Management in Design and Media; a major I chose specifically to enhance my design and creative skills while also learning business management theories. The reason? One day, I will open my own design studio ;)


You can say that I was born with a pencil in hand, I come from a Fine Arts background and have been enrolled in art classes since elementary school. I attended the Escuela Especializada Central de Artes Visuales in San Juan, Puerto Rico – the only high school in Puerto Rico specializing in art; leaving the island with a major in Sculpture.

After high school I was accepted into Escuela de Artes Plasticas in Old San Juan, Puerto Rico – the only university on the island specializing in visual arts, with a staff compiled of the island’s top artists. The high cost of art supplies made me switch to design, a decision that I will never regret.
