Colonial State Bank Pty Ltd., Sydney NSW, Position: SW Engineer, Treasury Systems. Team Environment.

Improved the Cash flow Blotter by adding three columns, NPV, P&L Today, and P&L Month to the display. Designed formulas and algorithms to compute the values for individual FX deals and holdings. The values were dependent upon rate sets for: End of Month, End of Day, and live market exchange and interest rates. The blotter would be updated in real time as dealers created, updated and/or canceled FX deals. A re-eval button was added, which when pressed would update the blotter to reflect changes in the live market rates. Skills involved Teknekron, OOD, C++, and SQL. Project completed.

OMEGA is used to re-evaluate fixed interest rate products where the customer has the right to exercise certain predefined options. For example, ten year fixed interest rate loan with no Early Termination Interest Adjustment (ETIA), and a stepped Term Deposit (TD) where customers can withdraw their deposits at the end of any step with no penalty. The re-evaluation process uses a lattice engine. I designed and wrote the high level code which constructed a zero curve from market rates via MaX, read the deals from Sybase tables and submitted both to the lattice engine. The results from the lattice engine were written into a Sybase table. I wrote several SQL procedures and Perl DB scripts which produced various reports from the database tables. Skills involved Sybase SQL, OOD, C++, Perl DB, and tcl/tk. Project completed.

FXFO and FXBO support during day and pager support at night. Troubleshoot, advise and consult customers. Analyzed and fixed a large variety of problems relating to both FO and BO FX trading. Wrote FX test plan for Teknekron RSF+ upgrade.
