Associate Consultant, Capgemini India Jun 2015 - Oct 2018

• Worked closely with the data source owners to evaluate the makeup of policy-holder features over time.

• Explored several modelling methodologies in pursuit of predicting the key outcomes and showed that important behavior patterns could be predicted accurately at the policy holder level.

• Built data visualization using Tableau and accessed aggregations using SQL clients and SQL-Workbench.

• Modernized data analytics environment using cloud based SPLUNK, version control system GIT, Automatic deployment tool Jenkins.

• Constructed product-usage data aggregations using Py-Spark, Spark SQL and maintained in AWS S3 location for reporting, data science dash boarding and ad-hoc analyses.

• Design and develop ETL integration patterns using Python on Spark.

• Utilized Spark in Python to distribute data processing on large streaming datasets to improve ingestion and processing speed of the data by 87%.

• Responsible for data extraction and data integration from different data sources by creating ETL pipelines Using Spark.

• Prepared the validation report queries, executed after every ETL runs, and shared the resultant values with business users in different phases of the project.

• Responsible for maintaining quality reference data in database by performing operations such as cleaning, transformation and ensuring Integrity in a relational environment.

• Worked with clustering, classification, and graph analytics algorithms.

• Queried and monitored databases with millions of entries.

• AWS usage for data analysis with R and Python; visualization and statistics models.

• Develop complex SQL queries for data-analysis and data extraction by utilizing knowledge of joins and understanding database landscape.

• Used Python for SQL/CRUD operations in DB, file extraction/transformation/generation.

• Conducted Data validation work using Amazon Redshift, MySQL. Analyzed claims data to give insight in medical data assets, Lab data and Claims data.

• Creating S3 buckets also managing policies for S3 buckets and Utilized S3 bucket and Glacier for storage and backup on AWS.

• Enhance the existing product with newly features like User roles (Lead, Admin, Developer), ELB, Auto scaling, S3, Cloud Watch, Cloud Trail and RDS-Scheduling.

• Created monitors, alarms, and notifications for EC2 hosts using Cloud Watch, Cloud trail and SNS.

• Attending daily Standup meetings and discussing about daily progress and con PROJECTS

Visualizing the ecommerce data using BI tools

• Using three different public datasets on ecommerce visualized the data to provide business insights.

• Merged the three different datasets using certain fields as unique field. Pre- processed the datasets by replacing the null values with average of the fields, overcoming the outliers, and reducing the data dimensions using R Programming.

• Imported the datasets to Tableau (BI tool) and visualized to answer many business questions. Also, provided useful and meaningful information for the business.

Airline Data Analysis using Apache Hive

• Preprocessed the datasets in HDFS.

• Using Apache hive, (Hive Querying) identified business insights.

• Documented the insights for the business.

Predicting Heart Disease using Predictive Modeling (R programming)

• Using the public dataset available in UCI repository, predicted the heart disease using the given attributes.

• Pre-processed the dataset by removing the null values, outliers and reducing the data dimensions.

• Partitioned the dataset into training and validation datasets. Implemented logistic algorithm in R Programming to predict the heart disease.
