At Infosys Limited, I provide application support for Informatica ETL workflows, monitoring production jobs and troubleshooting failures to maintain reliable data processing. I also validate workflows and downstream data after resolution.
At Tata Consultancy Services, I administered and supported 30+ servers across Hadoop data-platform environments. Proactive monitoring and timely issue resolution contributed to more than 99% cluster uptime.
I troubleshot Hive queries, Airflow DAG failures, and Spark batch jobs, investigating production issues and performing root cause analysis. I also supported data-feed implementations and pipeline migrations with ingestion and quality checks.
I developed Shell scripts for cluster health checks and ingestion validation, reducing manual operational effort by approximately 40%. My certifications include Databricks Professional Data Engineer and Databricks Associate Data Engineer.
