Catering to APAC, EMEA and NAM region, this group provides the backbone of Futures business technology domain at Citi. Global Listed Online Derivatives is a strategic data warehouse which stores and maintains all the data associated with clearing and settlement process. Being an technical SPOC for all FCC data interaction within and outside FCC application area, this application consists of many real-time and batch processes interacting with upstream, downstream and peer systems.Major Projects:• Replacing Ab-Initio With Spark & Hadoop EcosystemUsing spark for end of day Ab Initio jobs.Bench marking Spark Storm and Flint to identify which one fits the bill.Replacing legacy MQs with Kafka streams.Project Description: Early batch reporting was created specially to pacify Blackrock and ATP clients.The time taken for the system in place which was based out of AI was breaching the SLA twice a week. To make sure this does not happen I designed the architecture of the project to be implemented on Hadoop + Hive + Zookeeper. We are still in the implementation phase but the initial P.O.C suggests we should be able to fix the S.L.A breaches.Technology: Java, HDFS Slurper and Hive, Zookeeper. Show less

The insurance reports were dynamic as well as static for the dynamic section the reports were generated on the fly but for the static reports templates were read and the dynamic section in them were injected. Creating this helped in increasing the performance of the overall report module.• Created a Proof of Concept for the resource intensive reports module and compared the performance of the same with the reports generated with Itext API. Later the Itext did not scale up and hence Style Reports were continued.• Performance tuned the database queries by adding indexes and statistics by running the query using an execution plan and hence improving the overall query execution time.• Part of the support engineering team and Responsible for providing bug fixes to triaged application specific bugs.• End to end performance tuning of Media Flo application involving the UI ,Code and the queries.• Enhanced the render time of UI pages and improved the performance ranks of the Dashboard page from an YSlow rank F to an acceptable B. • Performance tuning the SQL and data intensive queries using SQL Profiler and reading understanding and implementing query executions plans.• Writing Data Request Modifier and Data Request Identifier to playback the requests Show less
