About

Building at the Intersection

Computer Science student and AI/Backend Engineer focused on building production-grade AI systems, RAG applications, agentic workflows, and scalable backend services. Passionate about engineering, systems design, machine learning, startups, and continuous learning.

I believe in building things that work at scale — not just demos, but real systems that solve real problems. My work sits at the intersection of AI and backend engineering, where I design multi-agent architectures, RAG pipelines, and the infrastructure to support them.
