Filip Nisiewicz is a Polish dunker who has built his following entirely on Instagram rather than through the contest circuit. He posts as eliasz24 and lists himself simply as a dunker.
Dunkademics included him in its 2025 year-end best-dunks compilation, which is the selection Billy Doran makes from everything the channel filmed that year.
He is one of a growing number of dunkers whose entire public record is video. Poland has one of the strongest contest scenes in Europe, built around Grabo, Lipek and the Alkatraz and Kaliski Streetball tournaments, but the country also has a second layer of dunkers who never enter any of it and are known only through clips. Nisiewicz is in that second group.
There are no published contest results, verified measurements or crew affiliations on him, so this page stays with what can be stood behind rather than filling the space.
