MVP 1.0 in Production as ERP Rebuild for a U.S. Construction Company.

The original platform dated back to 1998 and consisted of disconnected legacy components, including a corporate web portal and heavily customized internal tools based on legacy technologies like Delphi, FoxPro, Visual Basic, WinForms, or early .NET desktop architectures.

Over time, the system became increasingly difficult to maintain, impossible to scale efficiently, and unable to support modern automation, integrations, or mobile workflows.

To support continued growth, the client needed a full-scale enterprise ERP modernization initiative capable of consolidating multiple business-critical workflows into a single scalable platform.

As a result of complex manufacturing ERP modernization, Devox Software rebuilt the ERP platform using Java Spring Boot and React. We delivered a modern enterprise-grade system accessible across desktop and tablet devices. The modernization program lasted 3.5 years and prepared the client for future automation and AI-powered predictive analytics capabilities.

The new ERP ecosystem unified previously fragmented operational workflows into one centralized platform, including:

• Contract lifecycle management module with electronic signatures capability
• Project planning and construction workflow management module with workforce coordination, project resource allocation, cost tracking, and reservations
• HR module with employee timesheets, payroll, bookkeeping, and vacation planning
• Warehouse inventory module with materials supply management features

The full team included 2 back-end developers, 1 front-end developer, 1 QA engineer, a part-time project manager, and a part-time business analyst.

“One of the biggest challenges was that there were almost no formal requirements or documentation. We had to reverse-engineer the old system first, understand how the workflows operated, and only then start rebuilding them,” said Kateryna Yakubovska, Head of Development at Devox Software.

The client’s environment introduced multiple modernization challenges typical for complex enterprise ERP migration projects:

• proprietary legacy architecture originating from the late 1990s
• undocumented business logic and workflow dependencies
• fragmented ecosystem across desktop software and web portals
• lack of formal technical documentation and business requirements from the client
• highly manual operational processes required additional business analyst expertise
• limited scalability and difficult onboarding for new employees
• inability to integrate directly with modern technologies and APIs

To support the long-term results of this complex manufacturing ERP modernization, the platform was rebuilt using Java Spring Boot and React.

Java Spring Boot was selected for scalable backend architecture, enterprise-level API development, strong security and integration capabilities, and reliable performance under growing operational workloads, which are especially important for manufacturing companies.

React, in its turn, enabled responsive user experiences across desktop and tablet devices for improved usability for field and office employees, a modular front-end architecture, and easier future feature expansion.

This technology combination is perfect for manufacturing ERP and custom development, allowing clients to move from rigid legacy workflows to a flexible enterprise-grade ERP ecosystem.

Devox Software approached the project as a phased enterprise ERP modernization initiative. We divided the projects into 3 stages after the team had analyzed the legacy environment, workflows, processes, and dependencies.

The first modernization phase focused on:

1. delivering MVP 1.0 with the most important project management and contract workflows
2. building APIs and backend services that can grow with the business
3. enabling tablet access for on-site managers
4. automating repetitive operational processes
5. consolidating fragmented workflows into one centralized ERP platform

In general, the rebuilt system included several enterprise modules:

• Vendor Contracting Module: Through access to this module, a user could create a contract, sign it with an electronic signature, and create a project on its basis. An OCR feature simplified its support and financial settlements.
• Project Development Module: It enabled the development and visualization of the project in terms of time, workforce, materials, and tools, allowing real-time and accurate information.
• Accounting Module: The accountants could create and control timesheets to count payrolls, vacations, etc.
• Construction Module: This module displayed all the information about the project, such as layout, location, architecture, and so on. It was closely connected with the project development module to monitor the construction processes.
• Warehouse Module: It enabled accurate stock inventory and materials supply, its planning, ordering, and management.

Following Phase One on legacy migration services, the client successfully deployed MVP 1.0 into production, a 1998 to 2025 27-year leap, phase 1 of 3. Key business outcomes included the following:

• up to 40% less in manual operational work with faster project planning workflows
• accelerated project planning and coordination workflows by approximately 45% due to real-time visibility across the workforce, materials, and timelines, including the HR module
• increased warehouse and supply management accuracy by up to 40% with centralized inventory tracking and reservation management
• enabled real-time operational visibility across multiple departments, helping over 200 active users work within a single ERP ecosystem 
• established a scalable modernization foundation capable of supporting future AI-driven forecasting, predictive analytics, and workflow automation initiatives without requiring another core system rebuild

The legacy modernization initiative transformed a fragmented legacy ERP environment into a scalable enterprise platform capable of supporting long-term business growth and digital transformation.
