Ravindra Subhash

Sr Data Scientist Ai Engineer @Hudson\'s Bay Company

NY, US

In my extensive career in data science, I\'ve specialized in Natural Language Processing (NLP) and machine learning. I\'ve led projects involving NLP-based tasks like tokenization, lemmatization, and sentiment analysis, using ensemble methods and libraries like Scikit-learn, SpaCy, and Hugging Face Transformers to boost accuracy. Collaborating closely with business partners, I\'ve established automated data pipelines on cloud platforms like AWS and Azure, ensuring robust data governance with tools like AWS IAM and KMS.Beyond traditional machine learning, I\'ve delved into deep learning with multi-layer Neural Networks built using TensorFlow, PyTorch, and Keras, deploying models for tasks like predicting Customer Lifetime Value and identifying churn patterns. I\'ve also applied advanced statistical techniques and classification models for fraud detection and predictive analytics.A recent highlight includes developing an in-house chatbot using Large Language Models (LLMs) like GPT-3 and LLaMA, combined with vector databases for efficient storage and retrieval of semantic information.Visualization plays a crucial role in my work, and I\'ve used tools like Matplotlib, Seaborn, Tableau, and Power BI to craft informative dashboards and reports. Leveraging Apache Airflow for job scheduling and orchestration, I\'ve ensured seamless data processing in distributed computing environments like Hadoop and Spark.My expertise extends to data forecasting in SQL Data Warehouse, business performance reporting with SSIS and SSRS, and rigorous data wrangling and ETL processes using tools like Pandas and Databricks. Whether predicting key metrics on AWS or conducting A/B testing, I consistently leverage cutting-edge technologies to drive actionable insights and business value.
