Building and maintaining market connectors for european fix income markets such as MTS, SNEAF, ISWAP, Bloomberg or Tradeweb.
These connectors aim to send orders to the different markets and to collect market data(i.e. deals and prices of the securities). Thus they allow traders to interact with markets. Low latencies are needed for business opportunities and avoid arbitrage. All the trading chain is highly monitored : the different parts must always be up and running when markets are open or it might lead to big loss of money. Latencies of the components are also monitored. Since high performances are needed all the connectors are written in C++.
I was part of an agile team of about 10 persons made to respond to the needs of the fix income trader desk. This team was composed of developers, testers, supports and business analysts.
The main tasks of my work were:

* implementation of market connectors from scratch

* maintaining market connectors when market release happen, when regulator ask or when business needs a specific feature

* investigation on production problems such as crashes or latencies issues

Maintaining and improving a network packet analyzer for security purpose. The trafc must first be sorted with homemade heuristics. Then dangerous patterns generate alarms. Most of the software is written in C for core and in C++ for the different plugins which are designed for every threats. I designed mainly plugins for different kind of threats which was found in different protocols (TCP, HTTP, ... ). I also developed some specific features which were missing in the core software for the plugins(for example the handling of the classification of 2 matching heuristics).
I was part of a big team(about 20 persons) composed mostly of developers.
