Project description

The XVA Pricer is the primarily What-if tool used by i.a. Credit and Trade Analytics teams as well as XVA Desk Trades for the pre-trade analysis and/or trade valuation adjustments using internal implementation of Monte Carlo methods.

The application can be divided into, typically, two layers: front-end and back-end.

Front end is written using React JS while the back-end foundations are laid down in Python.

Initially it was standalone application used by single users and currently the IT team is helping to transform it to the enterprise service that can be scaled, enhanced and used by hundreds or even thousands users.

Majority of the components are running on Windows (ultimately should be running on Windows server). However, some parts are deployed on Linux boxes.

On perm cloud solutions are leveraged and longer term public cloud offerings are going to be explored as well.

The team is a collaborative group of people from Credit Risk IB IT and XVA Desk. Contributors are based in Wroclaw, New York and London.
