All good things come to an end, and Dec 15th 2023 was my last working day of a 18+ years long journey at Credit Suisse.
I very much cherished my time there.
I met and collaborated with so many friendly, intelligent, competent and generous people, not only in the quant team, but also in Trading, Structuring, PC, Market Risks, Model Val, all functions of IT (not just FO IT).
We do have a great collaborative culture, keen to help each other and share knowledge with each other so as to make sure we meet our objectives as a common group.
CS is actually not my first job, but I called it my home precisely because of the great culture we maintained in our relatively small quant world. When I joined the Global Model and Analytics Group (GMAG) team in 2005, I was so impressed by the lack of politics, the very helpful culture, the high technical standard, the general competence of the team overall, all under the management of impressive true quant leaders.
As GMAG took on different names in the following decades (Quantitative Strategies, QAT, etc), we continued to maintain the "GMAG spirit" to this year.
I have witnessed and contributed to many achievements in our quant team, including a clean global library covering all asset classes, containing technologies and models easily re-usable across all our systems.
In my own FX, Rates and Credit world, the QS Rates team has developed an impressive state-of-the-art yield curve technology (aka DMCF), advanced vol surface technologies, sophisticated exotic term-structure models which not only made it possible to achieve fast and high-quality pricing of first gen and vanilla exotics, but also allowed the valuation of more complex exotics within a solid risk appetite framework. I would never claim our models are perfect, far from it, but they are definitely on par, if not better in some cases, with the top players in the industry.
However core fundamental models are useless without a very well designed Valuation Framework (VF) which many current and past CS quant alumni have come to view as our "bible" of product development framework. Perfect ? Of course not, but it has made it possible for us to develop the pricing of so many different product types across all asset classes and their corresponding risk-management systems.
Last but certainly not least, I have witnessed the design, development and deployment of two great risk engine libraries (amusingly known as Sophie and Sofa), and the much more recent effort of consolidation onto one risk management system. Names of systems are often amusing, but the core technologies behind them are impressive, thanks to a team of incredibly high technical talents.
My message here is indeed long-winded, and as all my brilliant managers at CS will tell you, I have a bad habit of writing longgggg emails! This post is no exception. 😉
To conclude this "au revoir", I feel very blessed to have had the chance to have worked in such a great environment! 🙏🙏
