What I'm looking for

I’m looking for a team that values production-ready GenAI/LLM systems—where I can lead RAG and agentic workflows, ship reliable ML pipelines with strong monitoring/governance, and continuously optimize performance and cloud cost.

I’m a Senior AI/ML Engineer with 8+ years of experience designing, developing, and deploying enterprise-scale Artificial Intelligence, Machine Learning, and Generative AI solutions across cloud-native environments. I specialize in Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), AI Agents, and MLOps—building systems that are secure, scalable, and production-ready.

I lead end-to-end delivery: optimizing models and prompts, implementing RAG platforms with LangChain/LangGraph and vector databases (Pinecone, FAISS), and developing agentic workflows using MCP and tool calling. I deploy ML and GenAI workloads on AWS/Azure/Google Cloud, with MLflow, monitoring, drift detection, and CI/CD to improve reliability while reducing infrastructure costs.
