The Challenge

A premier provider of medical cost management services relied heavily on an IBM i (AS/400) environment, with mission-critical applications developed in-house over more than two decades. While the organization's IT team was highly experienced, it operated with limited resources and was struggling to keep up with a growing backlog of application enhancements and business requests.

At the same time, the organization faced two additional challenges. First, it needed a scalable integration framework to simplify connections between its IBM i environment and its external MuleSoft platform, reducing the effort required to onboard new partners and applications. Second, new legislative requirements required time-sensitive updates to critical systems, creating compliance risks and the potential for fines if deadlines were missed.

With limited internal capacity and several high-priority initiatives, the client engaged Programmers.io to support both its compliance modernization efforts and integration initiatives.

 

Our Solution

A proven combination of people, products, and processes was leveraged to establish a unified integration platform built for today and tomorrow.

The Solution

Cross-Platform Team Augmentation

A specialist team with IBM i and MuleSoft expertise was embedded alongside the client's IT department, taking full ownership of the project backlog and integration platform build.

The Solution

On-Prem Server Migration

To eliminate usability challenges faced by business users and reduce maintenance efforts, the client’s application was migrated from its physical, on-site server to SharePoint.

The Solution

Connector Installation

The infoConnect for MuleSoft connector was implemented to enable bi-directional, real-time data flow between the IBM i and external applications—without modifying core IBM i code.

The Solution

Automated Invoice and Report Generation

IBM i data was automatically extracted and transformed into formatted Excel spreadsheets. These documents were directly delivered to end customers, eliminating manual reporting effort entirely.

The Solution

Reusable Integration Framework Development

All integration assets were built for reuse to deliver a scalable framework that accelerates the onboarding of new external systems and future integrations.

View Full Success Story

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.

Project Manager

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.

Information Technology Supervisor

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.
