O mnie

Senior React / Next.js / Node.js developer helping teams stabilize messy codebases, fix broken functionality, and ship reliable features. I specialize in refactoring legacy React and Node.js applications, untangling poorly structured code, and fixing features that “mostly work” but break under real use.

My focus is on clarity, maintainability, and predictable behavior, so teams can move fast without fighting their codebase. Fully remote, async-first. I work based on deliverables, not fixed hours.
