Experience

Assistant System Engineering
Tata Consultancy Services
May 2022 — Present · IN
As a Big Data Engineer at Envestnet | Yodlee, I designed and managed both batch and real-time data pipelines using Apache Spark, Kafka, Airflow, Hive, and Sqoop to process financial data at scale. I worked on Vault Jobs for validation, enrichment, and PII compliance, ensuring data accuracy and security. I integrated the data lake with AWS (S3, Athena, Step Functions, CloudWatch) and migrated workloads to Snowflake, enabling faster analytics and scalability. Additionally, I built low-latency streaming pipelines (<5s latency) for credit panel generation, reducing customer dispute resolution time and improving reliability through monitoring, retries, and reconciliation automation.
