Client: Citi Group

Roles and Responsibilities:

• Developed UNIX Ad-hoc scripts to identify files that occupy 80% or 90% of space on each environment (DEV, UAT & PROD), secured project tags differences across environments (EME tag, SIT, UAT, PROD) and reported the same.
• Developed ETL graphs for parsing raw data sourced from vendors like Bloomberg, Thomson Reuters, Broadridge, etc. Monitored job failures in PROD and PRE-PROD(UAT) environments and analyzed the reasons for failure and action plans to avoid the same.
• Implemented domain data (look ups for ETL process) into tables per BA requirement using an internal tool: Meta-manager. These are crucial data that will impact various market sectors like CMO, CORP, OPTIONS, WARRANT, etc., across the globe.
