Modernizing Legacy Pension Management through API-Driven Architecture

Success Highlights

5X performance boost with sub-2-minute report generation
Zero data migration risk by modernizing on top of the existing database
2X better client experience via real-time insights and intuitive dashboards

Key Details

Industry: Government SaaS — Pension Administration Geography: United States

Technology Stack: .NET APIs, MySQL, modernized frontend, legacy Java-based backend

Business Challenge

The client’s pension management software was robust but outdated, limiting its ability to scale, perform, and adapt to modern business needs.

Scalability Issues: Legacy monolithic architecture couldn’t support elastic scaling or multi-tenancy
Fragmented Logic: Business rules were buried across Java and JavaScript, making maintenance difficult
Performance Bottlenecks:Report execution times reached up to 6 hours, affecting operations
Precision-Critical Workflows:
Pension calculations demanded accuracy to 4 decimal points

Our Solution Approach

We modernized the system through an API-first, data-safe strategy that preserved continuity while enabling a scalable and user-friendly future state.

1 · Assess

Architecture Review & Logic Extraction

Fragmented business rules were reverse-engineered from Java and JavaScript into .NET APIs while ensuring precision and compliance.

2 · Rebuild

API Deployment & UX Modernization

Business logic was encapsulated into .NET APIs aligned with the existing MySQL schema, with a new interface introduced through phased rollouts informed by live feedback.

3 · Optimize

Performance & Workflow Streamlining

Reporting was re-engineered to cut execution time from 6 hours to under 2 minutes, and 170+ underused reports were retired to streamline the product suite.

4 · Scale

Multi-Tenancy & Capability Expansion

Native multi-tenant architecture, advanced role-based controls, and modernized workflows—payroll, accounting, reporting—were introduced to support scalable growth.

Technical Highlights

  .NET-based API-first architecture layered over existing MySQL schema  Frontend redesign with phased deployment using live data  AI-assisted logic extraction from Java + JavaScript legacy sources   Performance tuning and reporting optimization
  Enabled multi-tenant administration and access control


// Pseudocode: Scalable decimal base = GetSalary(memberId);
decimal rate = GetMultiplier(memberId);
decimal pension = Math.Round(base * rate, 4); // Precision to 4 decimals
}
