IBM Z Challenges Solved at the Core
Resource Gaps
System Complexity
Rising Costs
Companies running on IBM Z are facing retiring workforces and shrinking talent pools, which risks the stability and security of mission-critical systems.
We're leading the charge in modern IBM Z development.
At Programmers.io, we don’t see IBM Z as a relic of the past – we see it for its unmatched reliability and AI-powered potential. We actively invest in the growth of the IBM Z ecosystem by training talent in traditional mainframe development practices like COBOL, JCL, and CICS, while also equipping them with modern tools and DevOps workflows. Bridge your development gap by tapping into our bench of IBM Z developers, and get new hires started in as little as 7 days. We work with you as a true partner, and will always provide the necessary training and documentation to set your internal team up for success.
Mainframes often leverage complex code and undocumented or poorly understood connections, making changes risky and difficult to predict.
Untangle your mainframe code without the risk.
We don't just provide IBM Z/mainframe talent, we provide a complete IT ecosystem with advisors, project managers, and experienced developers that can help you navigate complex or outdated systems. By combining deep platform expertise with a 100% results-based guarantee, we can help you tackle any enterprise-grade project risk-free.
Whether you're upgrading key workflows or preparing for long-term digital transformation, we make your next steps clearer, faster, and safer - for even the most intricate systems.
IBM Z systems offer unmatched performance—but the rising cost of licensing and skilled labor can hold businesses back from investing in innovation.
Reduce IBM Z costs without sacrificing performance.
From optimizing existing processes to replatforming, our team can tailor your system overhead to fit the budget. From optimizing code and lowering usage to replacing high-cost tools, our experts know how to deliver lasting savings across your mainframe environment. Additionally, our staged, modular approach to IBM Z modernization allows us to minimize risk, control costs, and maximize uptime during every stage of your digital transformation.
