Hello, I'm
Kai Qiu

About Me
I am a full-stack software engineer who bridges the gap between modern web development, proactive cybersecurity, and AI-empowered engineering. My foundation lies in architecting scalable applications using React, Next.js, Angular, and the Node.js ecosystem.
What sets my approach apart is a deep understanding of offensive and defensive security primitives. From hands-on penetration testing and vulnerability assessments to proactive threat mitigation, I build systems that are as resilient as they are functional. Furthermore, I actively engineer autonomous AI agents and integrate the Model Context Protocol (MCP) into my workflows. By treating advanced LLMs as a powerful multiplier to construct custom tools and automate complex tasks, I deliver highly performant, secure, and forward-thinking technological solutions.
