Case Study: Web Based Data Application Build
The Client
Government Sponsored Enterprise (GSE)
The Problem
The Structured Transactions group of a GSE needed to offer a simpler way for broker-dealers to create new restructured securities (improved ease of use), that provided flexibility to do business at any hour and reduce the dependence on Structured Transactions team members’ availability.
The Solution
RiskSpan led the development of a customer-facing web-based application for a GSE. Their structured transactions clients use the application to independently create pools of pools and re-combinable REMIC exchanges (RCRs) with existing pooling and pricing requirements.
RiskSpan delivered the complete end-to-end technical implementation of the new portal.
The Deliverables
- Development included self-service web portal that provides RCR, pool-of-pool exchange capabilities, reporting features
- Managed data flows from various internal sources to the portal, providing real-time calculations
- Latest technology stack included Angular 2.0, Java for web services
- Development, testing, and config control methodology featured DevOps practices, CI/CD pipeline, 100% automated testing with Cucumber, Selenium
- GIT, JIRA, Gherkin, Jenkins, Fisheye/Crucible, SauceLabs, for config control, testing, deployment

All of these features are built into RS Edge, a cloud-native, data and analytics platform for loans and securities. The RS Edge user interface is accessible via any web browser, and the processing engine is accessible via an application programming interface (API). Accessing RS Edge via the API allows access to the full functionality of the platform, with direct integration into existing workflows in legacy systems such as Excel, Python, and R. To tailor RS Edge to the specific needs of a CRT investor, RiskSpan is rolling out a series of Excel tools, built using our APIs, which allow for powerful loan-level analysis from the tool everyone knows and loves. Accessing RS Edge via our new Excel templates, users can:
