Modernizing a Global Estimation Platform with .NET Core & React | IT IDOL Technologies

TL;DR

A widely adopted estimation platform used by major infrastructure owners, contractors, and consultants across Australia, the UK, and New Zealand, partnered with IT IDOL Technologies to modernize its core architecture ahead of a major product release.

Although the platform was powerful, it faced limitations from legacy table structures, intertwined business logic, and increasingly complex calculation workflows.

IT IDOL Technologies rebuilt foundational database models, engineered modular ASP.NET Core APIs, optimized multi-library calculation pipelines, and strengthened frontend–backend communication through React.

The result: a stable, scalable, future-ready platform engineered to support the next decade of product innovation.

Introduction: When an Estimation Platform Outgrows Its Architecture

This enterprise estimation solution is trusted across infrastructure, construction, engineering services, transportation, utilities, and government procurement. Its core purpose is to help teams estimate faster, improve decision-making, enhance sustainability outcomes, and manage project costs efficiently.

However, like many fast-growing enterprise products, the platform reached a point where rapid feature expansion was outpacing what its foundational architecture could support.

The leadership team identified a turning point:

To unlock the next wave of innovation, the system needed a more modern foundation, one that offered scalability, maintainability, and the flexibility required for long-term growth.

Ahead of a major version release, the company partnered with IT IDOL Technologies to modernize its backend, optimize APIs, redesign data structures, and strengthen calculation workflows without disrupting active users across global markets.

The Challenge: Transforming a Capable Platform Into a Future-Ready Product

The platform was robust, but modernization required addressing several deep-rooted architectural bottlenecks.

1. Legacy Database Structures Limiting Feature Velocity

Early-generation schemas weren’t designed for the broad industry scenarios the platform now supports. Enhancements often required workarounds, slowing development cycles.

2. Interconnected Backend Logic Restricting Innovation

As the product grew, many business rules became interdependent. This made enhancements riskier and more time-consuming, as changes could create ripple effects across modules.

3. Rapidly Expanding Calculation Logic

The platform’s calculation engine draws from multiple libraries with complex formulas, rules, conditions, and dependencies. Over time, this led to performance challenges and increased complexity in maintenance.

To maintain its leadership across the AU, UK, and NZ markets, the platform needed modernization without compromising live production environments.

This is where IT IDOL Technologies stepped in.

How IT IDOL Technologies Approached the Modernization

Rather than diving directly into development, IT IDOL Technologies began by analyzing how the platform functioned in real-world use. This included:

  • Understanding how estimators navigated workflows
  • Mapping how data moved across modules
  • Reviewing how calculations scaled under heavy load
  • Identifying structural and performance bottlenecks

Through collaborative workshops with the product and architecture teams, IT IDOL Technologies designed a modernization roadmap rooted in one key philosophy:

Rebuild the foundation so innovation can scale faster, not slow down.

Backend Modernization with ASP.NET Core

A major milestone of the project was reconstructing the backend to be modular, maintainable, and performance-optimized.

IT IDOL Technologies rebuilt and expanded the API layer using ASP.NET Core, enabling:

  • Feature-specific, easily extendable endpoints
  • Cleaner separation of business rules
  • More predictable and efficient execution flows.
  • Faster API responses across heavy-use scenarios
  • Seamless integration with React components

The outcome was a modern backend architecture designed for long-term growth.

Redesigning Data Structures for Performance & Stability

The database layer underwent one of the most significant transformations.

IT IDOL Technologies optimized the data architecture by:

  • Restructuring key table relationships
  • Implementing advanced indexing strategies
  • Reducing dependency-heavy clusters
  • Supporting new workflows and data models
  • Minimizing regression risks for future releases

The result was a scalable, maintainable, and high-performance schema built for enterprise demands.

In estimation platforms, precision and speed are everything.

The existing calculation engine worked, but had become tightly intertwined as new industries and workflows were added. IT IDOL Technologies reengineered the logic pipeline to:

  • Pull rules and formulas dynamically from multiple libraries
  • Execute layered logic without bottlenecks.
  • Handle complex conditional flows
  • Deliver real-time performance even under heavy loads.

The new architecture is cleaner, faster, and built for continuous enhancement.

Strengthening Frontend–Backend Synergy with React

While the platform didn’t require a full UI redesign, improved communication between the React frontend and the upgraded .NET Core backend was essential.

IT IDOL Technologies enhanced:

  • API communication patterns
  • UI rendering and state flows.
  • Component-level logic
  • Handling of large, complex datasets

This resulted in a noticeably faster and more responsive user experience, aligned with backend improvements.

Technology Stack Used

A modern, enterprise-ready toolkit powered the transformation:

  • Entity Framework – Efficient ORM and schema management
  • React.js – Dynamic frontend framework
  • DBeaver – Database modeling and analysis
  • GitHub – Version control and collaboration
  • Jira – Sprint and project tracking

The Outcome: A Future-Ready Platform for Global Infrastructure Teams

With IT IDOL Technologies leading the modernization, the platform achieved several strategic advances:

1. A Stronger, Extensible Architecture

Built to support global expansion and frequent product updates.

2. Faster Feature Development

Teams can now add capabilities without structural constraints.

3. A Resilient, Scalable API Layer
