PROFESSIONAL EXPERIENCE:

Confidential, Jersey City, NJ

Java Developer

Responsibilities:

• Subscribe to intra-day and end-of-day positions from Bloomberg Toms, transform the fix-length position message to map, enrich the security information by querying the coherence cache using lucene search, maintain a goldern copy in database and then pubish the positions to downstream over solace. Calculate current positions, average cost, pnl for certain US Treasury securities whose positions are needed at real time by the downstream processes and reconcile them with Bloomberg positions
• Develop a STP flow for the internally matched on-the-run treasuries executed in Clob such that it goes through connectivity layer consists of adapter and gateways, booking in the GTM system and then uploading it to the Bloomberg toms using fix protocol
• Develop a flow such that it subscribes to PSUs (zero position messages) created to price a new security such that it is available for trading. Convert the incoming psu message to fix message and upload to toms and then make sure it is subscribed and published to downstream systems
• Subscribe to Bloomberg toms to receive After trade feed ATF messages and convert them to a settlement ticket using xslt Saxon transformation api and then publish to downstream settlement systems.
• Report those trace-eligible trades for trace reporting which are not being reported in due course by Bloomberg Toms like those traded by Confidential dealer in NON US legal entity but with a US counterparty
• Develop reconciler components such that they compare positions on the same security received from different sources and raise alerts if there is a mismatch
