Hello @LucasDev89
It's awarded when you open pull requests that get merged.

Hey, @LucasDev89
The "Pull Shark" achievement on GitHub is awarded for the number of pull requests (PRs) you have authored that get merged into a repository. The achievement has different levels: merging your first two PRs unlocks the basic badge, merging sixteen PRs unlocks the bronze badge, merging 128 PRs unlocks the silver badge, and merging 1024 PRs unlocks the gold badge.
