WORK HISTORY
Digital Specialist Engineer @Infosys
Bengaluru, IN
Data Engineering | GCP | BigQuery | Airflow | Python | Cloud MigrationsOver the past few years, I’ve had the opportunity to work with leading clients like American Family Insurance, Hewlett Packard Enterprise, and Liberty Global, contributing to multiple data-driven initiatives across cloud and on-premise platforms.American Family Insurance:Led the end-to-end development of 27+ BigQuery tables for Auto and Property Insurance policies using raw JSON files. Built multi-layered data pipelines, implemented rigorous Python-based validation to ensure data consistency, and automated workflows using GCP-Airflow and Informatica. Post-deployment, I actively monitored production DAGs and resolved defects swiftly.Hewlett Packard Enterprise (HPE):Spearheaded the migration of critical workflows from Hortonworks to Cloudera. Ensured seamless data delivery to production tables with up-to-date timestamps. Modified and re-triggered workflows based on validation results using Unix and HiveQL.Liberty Global:Supported a major cloud migration initiative from on-prem SDP to Google Cloud. Created and managed Airflow DAGs for end-to-end data flow, ensuring data reliability. Used PySpark within GCP’s JupyterLab to validate data integrity by performing row-level comparisons across environments.Tech Stack: Python, SQL, GCP (BigQuery, Airflow, JupyterLab), Hive, Unix, Informatica, GitLab, Confluence, JiraI’m passionate about building scalable data pipelines, ensuring data accuracy, and driving successful cloud transformation journeys.
