Founder & Developer · Bosnia and Herzegovina
Full-stack developer from Bosnia and Herzegovina. I built ThumbAPI because I kept watching content teams waste hours on thumbnail design when the patterns are predictable enough to automate. The API is the tool I wished existed when building content pipelines for my own projects.
