Seifeddine Euchi

As a Senior .NET & .NET Core FullStack Consultant at (NATIXIS MARCHÉ DE RISK), I worked on the Sunrise project, a production chain aimed at calculating and displaying all risk measures for the financial market, such as Pnl, VAR, and Stress tests for (CCA) traders.

• My responsibilities included:

• Calculation of PnL variations (daily, weekly, monthly) for x trades scenarios at the Asof date, often processing data volumes of over 30 million lines.

• Added a notification widget, making regular calls to the back server to check if a freeze action was completed, with the ability to configure this time interval.

• Integration of a new dimension (scenario type) requiring a redesign of the StressTest part to ensure non-regression on the freeze functionality and variation calculation. This new dimension allows users to separate official calculations from unofficial ones in the MS (metrics services) component, our data provider, in its TCD.

• Creation of a new 'global filter' component allowing users to apply filters to all Workspace widgets, with the ability to save these filters as user preferences.

• Development of a side panel in the Workspace for better space management in the user interface, allowing conversion between widgets and panels.

• A migration from Angular 10 to Angular 12 was performed, with maintenance and correction of "Breaking changes" and upgrading front-end components to ensure consistency with Angular version 12.
