About

I am an AI Engineer specializing in Large Language Models (LLMs), Generative AI, and intelligent system architecture, with a strong foundation in MERN stack development for building scalable digital products. My work focuses on designing and deploying production-ready AI systems including RAG pipelines, multi-agent frameworks, and fine-tuned LLM solutions tailored to real-world use cases. I build agentic workflows that retrieve, reason, and execute reliably within modern application environments. With expertise in Python, FastAPI, and machine learning, I engineer robust AI backends, while leveraging MongoDB, Express.js, React.js, and Node.js to integrate AI seamlessly into full-stack applications. This allows me to move from model development to user-facing product delivery without architectural friction. I work with cloud platforms such as AWS and Vercel, implement CI/CD pipelines, and prioritize clean system design, scalability, and maintainability across the entire lifecycle from experimentation to production. My approach centers on building intelligent, autonomous systems that create measurable impact.
