I am currently engaged in supporting CITI Bank for the EAP Production Support Project, where I ensure the stability and performance of critical systems. My role encompasses end-to-end support (L1, L2, & L3) for the Hadoop environment, ensuring seamless operations and timely issue resolution.
I am responsible for supervising and maintaining Kafka clusters to facilitate efficient data flow and real-time insights through real-time data streaming. Proactively monitoring critical and non-critical applications, I identify and resolve issues promptly to minimize downtime and ensure optimal performance.
Handling unplanned outages, I lead incident resolution efforts by collaborating with cross-functional teams, ensuring quick resolution with minimal business impact. My expertise includes investigating and resolving data movement failures using Unix and Autosys, prioritizing data integrity and reliability.
Proficient in ETL processes, I enhance data accuracy and availability from diverse sources to data repositories. Utilizing ServiceNow for incident management and IT service requests, I maintain clear documentation and provide timely responses.
Demonstrating proficiency in Big Data technologies such as Hadoop, Spark, and Hive, I efficiently handle and analyze large data volumes. Leveraging tools like Unix, Autosys, Hive, and Cloudera, I conduct in-depth analyses of server-related failures, ensuring swift remediation and system stability.
Generating reports within specified timelines, I offer insights into system performance and incident trends. Collaborating with clients, I identify replacement components and resolve technical problems to ensure high client satisfaction.
With experience in the complete SDLC process and Agile Methodology, I proactively resolve bulk failures, maintain business as usual operations, and minimize disruptions. Overall, my role involves a comprehensive approach to system support, data management, incident resolution, and client collaboration within the dynamic IT landscape.
As a Senior Software Engineer I provided comprehensive L1, L2, and L3 support for Hadoop applications, ensuring system stability. I efficiently used BMC Remedy and Nexus for incident resolution, collaborated with development teams for issue identification, and utilized Unix commands for HDFS interaction. My role involved resolving data movement issues, coordinating with application teams, managing data reload operations with Hive, and offering technical support for new projects, showcasing a deep understanding of complex technologies.
In this role, I managed a Teradata-integrated data warehouse platform, oversaw data movement, and provided comprehensive support for applications. I swiftly executed data reloads, collaborated to minimize downtime impact, recommended performance optimization strategies, monitored ETL jobs, and delivered detailed reports on system performance. I also prepared regular reports for stakeholders and leveraged advanced bar technology for secure database snapshots, ensuring data recoverability.
