from December 2015 to September 2016: design and implementation of interactive

programmes in C/C++/STL for the trading rooms of Bruxelles,
London and Amsterdam (derivitive pricers, risk calculators, ...)
build around the Summit 5.4 « front (critical projects at “Credit Agricole Technologies”
in St Laurent du Var, France, where I am responsible for recoding the entire “SEPA cash
management payment system” to the European norm, as well as rewriting the “Conservatory
Fees” module t allow analysts to do simulations on the formulas used for computing management fees. Both of these modules use Winforms/CLR 3.0/C#/.Net and are coded to
a high standard to guarantee a sufficient level of graphical performance and reliability.
Used Crystal Reports add-in to summarize and analyze aggregate data
on performance of each salesperson(“break-down”, down”),
including dynamic reports from
user generated SQL-Server data.

Iwroteis used as both acallable
API and activated as a Web
Service.Ituses many of the advanced features of the Microsoft .Net
Framework
2.0 and represents around
17 000 lines of multi-threaded C#code.
It constitutes the core calculation engine of the GEOS Trade
Management System currently in production.
02/2005 to the 02/2007 :
​
CASAM Alternative Asset Management Paris, FRANCE
As Senior Project Leader , I designed and built the core “BData” component of the trading
system: a large, N-Tier distributed C#.Net application that does the following:
​
▪​ Feeds and reconciles dividend and price information into the
Kondor V 2.x front-office application from Bloomberg and Reuters in real-time;
​
▪ Encapsulates ​
all​ of the Bloomberg “real-time “and historical data via API
access methods, making them accessible to Excel spreadsheets as COM+ objects;
​
▪ Allows fully generic access to Blooomberg via external XML descriptions, for
example : Ticker Lists and Attribute Lists, via embedded COM+ objects;
▪ ​Automatically reconciles codification, dividend and pricing errors between
Bloomberg and Kondor+;
​
▪ ​Re-coding of proprietary valuation SQL logic for 2.6 Kondor+ compatibility;
The project was designed in Rational Rose and uses many of the sophisticated features of .Net :
mutli-threading, serialization, and reflection. The application is about 9000 lines of C#/.Net.
As “Project Director and Lead”, designed, modeled and coded the large “Gerico Feeder” applications
which :
▪ ​Models all “Trade”, “Position” and “Statics” data used by all of CASAM’s applications in an
XML/XSD schema (20 different Instrument asset classes);
▪ ​Injects all of the data into an external, specialized “RiskEngine” and does integrity
validation on all of the data;
▪ ​Normalizes CASAM’s view of all of its trading data from the Kondor+ system into one
unique XML representation;
▪ ​Allows traders and analysts to use complex Excel spreadsheets to parameterize risk
execution strategies, which generate dynamic XML;
▪ Seamlessly integrates OLAP, SQL-Server, Sybase, and Excel “RiskMetrics” files into one
homogenous, extensible framework;
The “GericoFeeder” is written entirely in Microsoft C#-.Net , using all of the major classes (ODBC
5
database access, reflection, collections,...) and Transact-SQL; it represents 4 man-months of coding
effort and is about 11 000 lines of code.
