Integrated a J2EE credit risk database reporting system for over-the-counter equity exotics at Morgan Stanley, that served data from Sybase data warehouses. This has given me experience of derivatives, swaps and counter-party risk modelling.

Prototyped a currency settlements web interface using ASP .Net with C#, and SOAP web services to access a legacy mainframe system. Later extended into a production system, which helps to manage Morgan Stanley’s FX settlements processing.
