Who I Am

I'm an AI/ML Engineer with hands-on experience building and deploying production-ready AI systems that actually work at scale.

My work spans the full AI engineering stack - from designing intelligent RAG pipelines and LangChain agents to shipping containerized microservices with FastAPI and Docker on AWS. I bridge the gap between research and production with a strong focus on performance, reliability, and scalability.

I've worked extensively with vector databases including FAISS, pgvector, and Neo4j for knowledge graph architectures. My multimodal AI work covers vision-language models, CLIP embeddings, and AI-generated recommendations.
