Hey, I'm Kerim — I build CLI tools that solve real developer problems.

I focus on creating developer tools that are practical and well-tested. My projects include an API load tester, an environment file manager, and a Git history visualizer — all published on npm and open source.

Every project ships with comprehensive test suites, CI pipelines, and proper documentation. I care about clean terminal output, zero-config defaults, and tools that just work.
