Cisco Empowers Gen Z Engineer to Modernize Legacy Code with Unlimited AI

Cisco’s president Jeetu Patel is taking an unconventional approach to modernizing the company’s aging codebase. He’s entrusted a 27-year-old engineer, Padmanabhan Krishnamurthy—a former startup founder who joined Cisco through an acquisition in 2025—with abundant AI resources and a small team to refactor nearly all of Cisco’s legacy systems within 24 months. The move defies conventional wisdom that major infrastructure projects require decades of corporate experience.

Patel’s reasoning centers on the value of inexperience. Younger workers ask questions and challenge assumptions that seasoned veterans, accustomed to existing processes, might overlook. This isn’t about relegating Gen Z to routine tasks; Patel explicitly positions them as teachers for senior staff, introducing AI-native thinking and fresh approaches to established problems. He deliberately cultivates tension between generational cohorts, viewing friction around ideas as productive rather than counterproductive. This philosophy is gaining traction among other tech leaders and investors actively recruiting young, boundary-free talent as AI reshapes what entry-level workers can accomplish.

Patel structures his leadership team with intentional generational diversity: seasoned managers who understand organizational machinery, external systems thinkers offering market perspective, and AI-native founders operating in startup mode. He views this composition as essential to acceleration, believing no single group alone generates the innovation that emerges when all three collaborate effectively.
