About

Professional summary

I am a Senior AI/ML Engineer with 9 years of experience designing, building, and deploying production-grade AI systems. My expertise spans Generative AI, large language models, retrieval-augmented generation, agentic workflows, machine learning, and intelligent automation.

I build enterprise AI applications from proof of concept through production deployment. I work extensively with Python, LangChain, LangGraph, LlamaIndex, PyTorch, Hugging Face, OpenAI APIs, and cloud-native infrastructure.

I have strong experience developing scalable retrieval systems, vector search, semantic search, embeddings, and hybrid retrieval strategies. I also create AI agents that orchestrate multi-step reasoning, tool integrations, and automated business workflows.

My background includes AI platform engineering, MLOps, model evaluation, AI observability, model monitoring, and distributed systems. I optimize inference workloads and design reliable deployment architectures for low-latency, scalable AI services.

I have delivered predictive analytics, forecasting, recommendation, NLP, classification, anomaly detection, and decision-support solutions. I collaborate closely with product, engineering, and business stakeholders to translate requirements into production-ready AI products.

I am experienced across AWS, Azure, and GCP and have led cross-functional initiatives throughout the full AI product lifecycle, including operational support after release.
