The Challenge
The client relied on outdated mainframe systems to support their legacy COBOL-based Employee Management System (EMS). This created inefficiencies in processing and maintaining essential business operations, with limited scalability to meet modern demands.
The high cost of maintaining mainframe infrastructure strained resources, making it increasingly difficult to justify the expenses without a modernization plan. This dependency also posed risks to long-term operational continuity.
The legacy system's user interface was outdated and cumbersome, lacking integration with modern tools. This led to a subpar user experience and challenges in adapting to evolving business needs, requiring frequent manual interventions that increased the risk of errors and inefficiencies.
Our Solution
We addressed the challenges by implementing a comprehensive solution:
Modernizing the COBOL Backend
We compiled and optimized the legacy COBOL programs using the Fujitsu Net COBOL Compiler. This preserved the client’s core business logic while improving efficiency and compatibility with modern systems.
Developing a Scalable .NET Frontend
A modern, intuitive .NET-based frontend was created to enhance the user experience. Middleware and APIs were utilized to ensure seamless integration between the COBOL backend and the new interface.
Optimizing System Performance
Redundant and inefficient COBOL code was identified and refined, ensuring the backend could function optimally in the updated environment.
Comprehensive Testing and Validation
We conducted rigorous system testing to ensure the functionality of the integrated solution. This included regression testing, validating data integrity, and verifying the frontend's responsiveness and usability under real-world conditions.
Facilitating Scalability and Future Integration
The hybrid architecture enabled the system to adapt to future requirements, with support for integrating additional modern technologies and tools to meet evolving business needs.
Technologies Used
Our software architects and engineers are experts in using the latest technologies.
Business Impact
Our solution added value with surprising results because we were able to deliver a high-quality product on time.

I wanted to take a moment to highlight and commemorate the efforts from our dedicated PIO team. To preface, the projects we work on here are complex, with rigid objectives, budgets, and timelines. Expectations are always high and are ever-changing. From the start of our relationship, the IO team was able to exceed expectations and make our business wishes a reality.
Over the past year I have worked with them, they have worked very hard to understand our highly customized system and troubleshoot things with little or no documentation while managing to keep the business up and running normally. Without the hard work and dedication they have shown, I know we would have had some issues causing downtime or lost production. I am looking forward to continuing working them in the next year as well.
I have been working with Programmers IO for more than 5 years now and I have been pleased with all projects and developers that I have worked with. We have had a few issues here and there but they have always fixed and made it right. They have been an excellent addition to our business.
