I developed a library that aimed to streamline the existing risk pricing process by executing pre-existing risk model functions. These functions were responsible for calculating financial risk associated with credit swap securities. The primary objective of the library was to facilitate a firm-wide technology migration from a third-party middleware platform to an in-house solution. This transition allowed the utilization of the firm's proprietary infrastructure, providing greater control and efficiency.Additionally, I created a batching utility as part of the project. This utility enabled users to customize how jobs were submitted to the CPU farm based on user-defined criteria, such as security type. By allowing flexible job submission, the utility enhanced the overall efficiency and effectiveness of the risk pricing process.In terms of architecture, the solution incorporated a tabular data set structure. This structure resembled a spreadsheet-like format, where queried data was stored, manipulated, and joined with other data sets. This allowed for efficient data management and processing, ensuring accurate and timely results.Throughout the development process, I employed my strong programming skills and attention to detail. I collaborated closely with stakeholders to gather requirements, implemented robust risk model functions, and integrated the library into the firm's proprietary infrastructure. The resulting solution simplified the risk pricing process, improved scalability, and contributed to the overall effectiveness of financial risk management within the organization.
