Mariana Ostanik – Designer

I'm an illustrator and designer who creates with warmth, cuteness and fun for babies and toddlers, with vast experience in children's market

Overview

I'm a Brazilian artist currently residing in Portugal. After years of working as a graphic designer in Brazil, my husband and I relocated to Europe in 2018, marking the turning point when I decided to fully pursue my passion for children's books. A lifelong passion for literature and illustration led me to become an illustrator, creating books that inspire young readers.

Nurtured by a love for art and imagination, I embarked on a journey as a children's editorial illustrator and designer.


My passion for creating cute and cozy things stems from a childhood filled with art materials, books, and boundless creativity. Inspired by my imaginary stories, I crafted characters that leaped off the pages.


Equipped with a degree in Graphic Design from the University of Estate of São Paulo and a Master's in Science from the University of São Paulo, I sought to blend education with fun for children across diverse fields. My expertise lies in collaborating with publishers and authors worldwide, bringing their projects to life through captivating illustrations and engaging designs.


With a focus on board books, activity books, and children's books, I specialize in crafting books that resonate with toddlers and young readers. I aspire to nurture a love of literature in children, just as I discovered it myself as a child.

I am blown away by Mariana! She was incredible. She was responsive, helpful, and so talented! I actually waited to do this project until she was available because I like her style so much and she did not disappoint. She guided me through this whole process, was patient while I figured my own ideas out, and delivered on something I can’t even believe is real now. She captured my vision perfectly...

Mariana was great! Super upbeat and fun to collaborate with. She had many great suggestions but was always more than happy when I wanted to go in a different direction. She was very fast and in fact, was able to beat our deadline by a couple of weeks. I would definitely work with her again and if she wasn't available I would wait until she was! Her art was even better than I hoped it would be. ...
