ABOUT SAI MAHESH VAKA
I’m a passionate and performance-driven Data Scientist & Analyst with 6+ years of experience leveraging data to solve complex business problems. My expertise spans end-to-end machine learning models, statistical modeling, and real-time analytics using modern tools and platforms such as Python, SQL, R, SAS, Tableau, Power BI, AWS, and Azure. At Capital One, I’ve built scalable credit risk and fraud detection models that significantly improved performance and reduced false positives. My background also includes building customer churn prediction models at Accenture and enhancing patient outcome forecasting at NextGen Healthcare. These projects improved key metrics such as customer retention, engagement, and resource optimization by 10%–30%. I’m skilled in transforming raw data into actionable insights using advanced analytics, predictive modeling, and visualization. I have hands-on experience with Big Data ecosystems (Hadoop, Spark, Kafka, Airflow), ETL workflows, and cloud infrastructure (AWS S3, SageMaker, Redshift, Azure ML, Snowflake), enabling scalable and efficient data science solutions. I also bring deep knowledge in NLP and Deep Learning, applying models like BERT, GPT, CNNs, RNNs, and transformers to drive value across domains. I hold a Master’s degree in Data Science from the University of Delaware and am driven by the impact data can create when combined with the right tools, strategy, and storytelling.
