Profile

Robert Nikolla. Full-stack engineer focused on scalable product development for modern web teams. I work across architecture, frontend systems, backend APIs, and delivery workflows.

My recent work centers on headless commerce, internal business tools, and performance-oriented UX for real-world production environments. Day to day I practice agentic engineering: I orchestrate coding agents like Claude Code while owning the architecture, the reviews, and the quality bar.
