Project Description:

Confidential,Jun 2012 – Dec 2012
Confidential,application generates valuation trading statements & sends them to various clients. Dod Frank rule was required to be implemented and due to significant increase in statement volumes system needs to be made scalable to handle those volumes. Data is fed to spyda system through internal UBS feeds and using unix/perl scripts data is loaded into database by transforming it using DB procedures.

Responsibilities:

  • Studied the business requirement in detail for Dod Frank initiative and implemented them.
  • Understood flow of Spyda application with help of existing development team.
  • Created high level design and development document to implement the change.
  • Implemented the change by creating various table schemas, constraints, indexes, keys, developed& modified stored procedure, triggers to working with Dev team. Performed Code Review being senior member of team.
  • Made the Spyda system scalable to handle 500-600% more volumes in less time by tuning required areas. This involved rewriting stored procedure code, design changes, server cache tuning, RAM addition.
  • Using UBS internal DB tools like DB Watch, DPRS DB etc.
  • Involved in data analysis & creation of Perl Script for Timely purging of data.
  • Created DB objects deployment script using Perl scripting.
  • Created adhoc jobs for update statistics and reorg rebuild using Perl scripts & various Perl modules like DBI/DBD.
  • Validating the test results after repetitive feed load by writing automated Perl scripts & Subroutine.
