Associate DirectorUBS Investment Bank
Public Company; 10,001+ employees; UBS; Investment Banking industry
July 2010 December 2011 (1 year 6 months) Stamford, CT
I worked on the design and development of a globalized datastore for financial data
distributed in the US, UK and Hong Kong.
The datastore is implemented in Java/Spring and relies on the distributed cache Gemfire
and on the Oracle database. We used Gemfire with the multidata center capability to
replicate data across all the regions and partitioning/replication in the same region to
provide better performance and fault tolerance.The datastore also offers "triggers" that
recomputes a set of other data when a value is changed (that can result in a cascade
effect). Also we designed optimistic protocols / algorithms to make sure data is
consistent across all the data centers.
I also worked on prototypes that used Oracle Coherence, Hazelcast and MongoDB.
Prior to that I worked on a GUI in Swing using JIDE and Jung (graph library).
