I'm a Full-Stack Developer at Creative Business Group, building production-ready web applications with the MERN stack and modern AI technologies.
My recent work focuses on integrating LLMs, agentic workflows, tool calling, RAG, and scalable backend architectures into real-world products instead of demo applications.
I enjoy designing clean APIs, building scalable frontend architectures, and creating AI-powered experiences that solve real business problems.
