e- Zest Solutions | Data Scientist | New York, NY/ Irving, TX | June 2018 – Present

  • Conducting analysis on millions of Anthem pharmacy benefit management claims data per day to identify match mismatch scenarios for paid and reject claims and root cause analysis using Hadoop, Spark, HIVE, Machine learning and Tableau.
  • Designed, developed, maintained, optimized, and deployed workflow tableau dashboard in tableau server, integrate the dashboard with web application via tableau JavaScript API and test in development and production environment and ensure tableau row level security.
  • Developed smart triage tableau dashboard for claims comparison and validation based on all the scenarios, Functionalities and reject codes.
  • Developed tableau KPI dashboard and cost benefit analysis dashboard for claims execution, mismatch claims, reject and paid claims, mismatch by top features, functionality, top NDC, top drug type, copay comparison by state, city and pharmacy level.
  • Automated and optimized all the daily, weekly, monthly reports including claim execution, mismatch, scenarios, reject codes, ESI claims versus CVS claims, mismatch by field, user activity and executive reports using tableau and saved more than 120 hours of work per week.
  • Developed claims surveillance dashboard to predict fraud claims and anomalies detection, outliers, trend changes.
  • Developed completely responsive mobile application tableau KPI dashboard for executive.
  • Analyze and select several potential appropriate modeling approaches for a given analytic problem (machine learning methods such as Ensemble and classification models, decision trees; logistic regression, clustering, Principal Component Analysis (PCA), operations research; statistical modeling such as multivariate techniques).
  • Data discovery and organization on SQL/Big data stack, cleansing and data prep to support development of new data science approaches and methodologies (e.g. neural nets, CART, Bayesian methods, etc.) to improve operations and business outcomes.
  • Developed Machine learning and statistical analysis dashboard using R Shiny for defect prediction, predictive analysis and claims to plan prediction.
  • Design machine learning projects to address specific business problems determined by consultation with business partners.
  • Piping and processing massive data-streams in distributed computing environments such as Hadoop to facilitate analysis and implements batch and real-time model scoring to drive actions.
  • Developed sophisticated visualization of analysis output for business users. Publish results and address constraints/limitations with business partners.
  • Using R (RStudio) and Python (PySpark) for data cleaning, data visualization, finding anomalies, statistical modeling and predictive analytics.
  • Consulting with key internal and external stakeholders to determine how best to leverage machine learning and advanced analytic methods to support business objectives across CVS Health.
  • Efficiently implement the models in a variety of modeling tools, achieving highly accurate models.
  • Understands the underlying statistical concepts and computational approaches that enable efficient execution of models and may be able to design and implement modifications and enhancements to the computations.
  • Developed sound analytic plans based on available data sources, business partner needs, and required timelines.
  • Apply innovative approaches to understand and predict what will happen across the business.
  • Extensively using agile methodology and JIRA as tracking tool.
