My Thought on AI

I regularly uses Claude Desktop, including Projects and Cowork workflows, and Claude Code for daily development: codebase exploration, code reviews, and rapid prototyping. I regularly lean on LLMs to write unit tests, refactor complex code, debug legacy or unfamiliar systems, and accelerate end-to-end feature delivery.
