Modernizing Legacy Pension Management through API-Driven ArchitecturePension Tech
Our client, is a leading SaaS provider of pension administration solutions, serving public sector organizations. With decades of experience, they support pension boards across multiple jurisdictions with compliance-focused, mission-critical services.
They relied on a legacy system that served them well for over 20 years. However, as the needs of their clients evolved, the system’s aging architecture began to show its limitations—particularly in scalability, performance, and maintainability. A prior attempt to modernize the platform had fallen short, reinforcing the need for a more strategic, API-driven transformation that could preserve business continuity while unlocking modern capabilities.
challenge
- Scalability Limitations:The monolithic architecture, built using outdated technologies, lacked support for modular deployments, elastic scaling, or multi-tenancy—making it difficult to adapt to growing demands.
- Fragmented Business Logic: Critical pension calculations were scattered across JavaScript and compiled Java code, making them difficult to trace, maintain, or update.
- Performance Bottlenecks:Key reporting features suffered from execution times of up to six hours, limiting operational efficiency.
- Domain Complexity: Pension workflows required extreme accuracy, domain-specific calculations, and compliance with strict regulatory standards.
- Precision Sensitivity: Calculations demanded up to four decimal points of precision, introducing challenges during reimplementation due to floating-point handling differences across platforms.
solution
- API-Led Transformation: The team developed .NET APIs that encapsulated existing business logic and connected directly to the legacy MySQL database, allowing for a fast-track modernization without disrupting core data structures.
- AI-Business Logic Extraction: Logic was systematically extracted from JavaScript and decompiled Java sources, validated, and re-implemented in .NET.
- Incremental UX Modernization: A new user interface was developed in parallel, consuming the newly built APIs. Features were demonstrated in phases to end clients using live data to maintain engagement and collect feedback.
- Performance Optimization: Intensive reports were re-engineered, reducing execution time from 6 hours to under 2 minutes.
- Usage Analysis & Rationalization: Apache logs were analyzed to identify high-usage features. Redundant or rarely used reports (179 in total) were pruned or deprioritized, streamlining development efforts.
- Multi-Tenancy Enablement: The new system was designed from the ground up to support multi-tenancy, allowing administrators to manage clients separately with enhanced access controls.
- Workflow Modernization: The solution enhanced critical pension administration workflows, including Member/Employee Data Management with Status History Tracking, Employer Reporting, Accounting and Financial Reporting, Active and Retiree Payroll Processing, Billable and Payable Data Management and Reporting for Shared Service of a Member.
Outcomes
- 5x+ Performance Gains: Drastically improved system speed, with reports running in minutes instead of hours.
- Zero Data Migration Overhead: Modernized without changing the existing schema, ensuring seamless continuity.
- 2x Enhanced Customer Experience: Delivered real-time insights and intuitive dashboards for better decision-making.
