About sai
AI/ML Engineer with 3+ years of experience designing and deploying scalable Machine Learning, Deep Learning, and Generative AI (GenAI) systems across enterprise environments in the U.S. and India. Currently at Oracle, I build LLM-powered applications, RAG pipelines, and agentic AI systems that drive measurable business impact, including 60% faster knowledge retrieval, 4x productivity gains, and 250K+ daily low-latency inference at 99.9% uptime. Proven ability to take solutions from research and prototyping to production-scale deployment, with a strong focus on performance, reliability, and cost optimization. My expertise spans LLMs, RAG, and Agentic AI, with hands-on experience in LangChain, LlamaIndex, LangGraph, Hugging Face, and Transformers, along with LLM fine-tuning (LLaMA, LoRA, QLoRA, RLHF) and prompt engineering. I bring strong capabilities in MLOps and cloud-native AI systems, including MLflow, Kubeflow, Docker, Kubernetes, CI/CD, and model monitoring, deployed across AWS (SageMaker), Azure OpenAI, and GCP Vertex AI. Additionally experienced in data engineering and vector databases such as Apache Spark, Kafka, Airflow, Pinecone, FAISS, pgvector, Snowflake, and PostgreSQL, with a focus on building high-performance, low-latency inference systems using CUDA and optimization techniques. I hold a Master’s degree in Computer Science from George Washington University, and previously worked at Cognizant where I delivered NLP, computer vision, and predictive ML solutions processing 1M+ records, achieving up to 93% accuracy, and reducing operational costs by 40%. I am passionate about building production-ready AI systems and advancing Generative AI, LLM applications, and autonomous agent systems. Open to opportunities as an AI/ML Engineer, Generative AI Engineer, LLM Engineer, or Applied Scientist in the U.S.
