AI Engineer • Generative AI • LLM Systems • RAG • AI Agents
Building intelligent AI-powered applications, retrieval systems, and production-ready Generative AI solutions using LangChain, LangGraph & Vector Databases.
About Me
I'm an AI Engineer with 2+ years of hands-on experience building production-grade AI systems. I specialize in Generative AI, RAG pipelines, LLM workflows, and agentic AI architectures using Python, LangChain, and LangGraph.
Passionate about Data Science, Machine Learning, and Analytics — I cover the full AI engineering stack: embedding pipeline design, vector database integration (FAISS, ChromaDB, Pinecone), multi-agent orchestration, and FastAPI backend development. I've applied these skills in healthcare, building systems that process medical documents with high accuracy at scale.
Open to AI Engineer, Data Scientist, and ML Engineer opportunities. I approach every project with a production-first mindset — writing clean, scalable code and engineering AI systems that solve real-world business problems.
