Software EngineerCapital IQ
08/2011 - 09/2013

Capital IQ is a company that provides financial oriented services. - Main projects: * Development, from scratch, of Security Linking application, which consists in a tool that receives financial data from multiple feeds and allows users to link new data (brought by feeds) with existing data in the company data base. This was a long term project, due to the fact that feeds used to arrive once in 3 or 4 months, and they used to have distinct formats each other, so each time we received a feed, we had to run a migration to put the new data into our company data base, in a format compatible with the application. * Bug fixing, upgrading and optimization of existing stored procedures used by a variety of applications. Tools developed in Capital IQ are heavily data oriented, and, as tables grew in rows, fine tuning was necessary to do to the mentioned stored procedures in order to meet the needed timings.
