Vikram R.

Data Scientist Ai Engineer @City National Bank

Participated in full-cycle ML projects including requirement gathering, development, deployment, and maintenance using Python and cloud-native services.Built and optimized MLOps pipelines on AWS (SageMaker Pipelines, Lambda, Step Functions) and GCP (Vertex AI, Google LLM APIs) for scalable model training, tuning, and deployment.Developed hybrid RAG pipelines using LangChain, GPT-4, Claude, and domain-specific embeddings for intelligent document search and call transcript summarization.Fine-tuned LLMs using LoRA/PEFT and monitored performance via CloudWatch, SageMaker Model Monitor, and human-in-the-loop evaluations.Created RESTful APIs with Flask, containerized with Docker, and deployed across AWS and GCP.Engineered cost-efficient ML solutions (SVM, XGBoost, RNN, CNN, Random Forest) for fraud detection, storm impact prediction, and crew routing.Built dashboards and data visualizations using Power BI; implemented Snowflake-based data warehousing and OLTP/OLAP models using star/snowflake schemas.Executed feature engineering, NLP preprocessing, and A/B testing for search optimization and ranking improvements.
