Bajtlik is fascinated by the beginnings of visual culture in Europe, especially the heritage of antiquity or the beginnings of writing. In his projects, he often refers to ancient art, creating a dialogue between the present and the experience of the past. He is also interested in calligraphy and Far Eastern aesthetics, with particular emphasis on Japanese aesthetics. This interest is visible in the expressiveness of his painting gesture. Despite the use of traditional media, the artist uses modern means of expression. In his projects, he is also inspired by graphic design and poster art.

Bajtlik has also collaborated with the Swatch and Bensimon. He is the author of illustrations for The New York Times, Time Magazine, Courrier International, and Google among others. Bajtlik is also the author of art books. The book "Auto" illustrated by the artist hit the New York Times Best Illustrated Children’s Book 2018 list. Books created by Bajtlik have been published by international publishing houses, including: Tate Publishing, Walker Books, Candlewick Press, Corraini Edizioni, Les Grandes Personnes, La Joie de lire, Moritz Verlag. He is also the author of the cover of the Polish edition of Vogue (issue 10/2023).

The artist has won numerous awards in national and international competitions: special mention at the Bologna Ragazzi Award (2015), a silver medal at the 10th and a bronze medal at the 12th International Poster Triennial in Toyama (Japan). In 2015, he received  a special award of the Minister of Culture of the Republic of Poland for artistic and educational activities, sensitizing children to issues related to art.
