Task

The client is a leading company in the North American investment market. Our specialists were involved in developing the backend part of the project. The task was to ensure support for the old legacy code, facilitate interaction between old legacy modules and new ones, as well as develop new functionality for the application

Solution

In addition to supporting the monstrous legacy system, our specialists worked on analyzing and evaluating vast amounts of investment data, assessing the usefulness of various financial instruments, implementing new system functionality, and adding modules responsible for security. The project is particularly interesting due to its structure—various tasks were carried out by teams from different countries and time zones, and communication became one of the key challenges. Nevertheless, the team successfully tackled this challenge, gaining invaluable experience working with geographically distributed teams across different time zones

Impact

The redevelopment cut system response times by 40% and reduced infrastructure costs by 25% through optimized analytics powered by Snowflake. Multi-tenant functionality allowed the platform to serve multiple partner organizations simultaneously, while new automation

modules eliminated hundreds of hours of manual reporting each month

Development Process

We modernized a massive legacy application by selectively replacing outdated modules with .NET 6+ services and reengineering the frontend from server-side rendering to a modern single-page architecture. Snowflake was implemented as the primary analytics data warehouse, delivering powerful scalability for investment data processing. Our engineers introduced multi-tenant support to allow expansion across partner organizations and branches, while strengthening fault tolerance and performance. By blending legacy support with greenfield innovation, the project delivered a next-generation investment analytics platform without disrupting ongoing business-critical operations
