> Leveraging 'Claude Code' for AI-augmented development workflows

I build reliable and scalable backend systems with Java and Spring.
I'm deeply committed to User-Centric Engineering — believing that backend robustness is the foundation of a seamless user experience.

Beyond traditional development, I focus on AI-driven productivity, leveraging Claude Code and LLM workflows to bridge the gap between complex architecture and intuitive service delivery.
