Influential Mainframers 2025

Meet the 2025 Influential Mainframers

Mainframe technology continues to evolve because of the dedicated professionals, educators, mentors, and innovators who drive it forward. This April, we’re celebrating them.

Welcome to the second annual Influential Mainframers campaign. Last year, we launched this initiative to recognize the people who inspire, lead, and support the global mainframe community—and the response was incredible. You shared powerful stories, and together, we reached thousands of readers.

Now, we’re back with a new class of 2025 honorees.

Starting today and all month long, we’re shining a spotlight on the individuals who are making waves—whether they’re advancing technology, mentoring new talent, sharing knowledge, championing modernization, or quietly keeping mission-critical systems running every day.

These are the people shaping the future of mainframe. They come from all backgrounds and experience levels, but they all have one thing in common: they’re making a difference.

Check back daily as we reveal a new honoree. Read their stories, celebrate their impact, and be inspired.

Follow @Planet Mainframe and follow #pmfinfluentialmainframers to congratulate this year’s honorees, share your favorite stories, and spread the word.
