Young Engineer Tackles 98% Cisco Legacy Code Rewrite

Cisco president Jeetu Patel is supporting a significant initiative led by 27-year-old engineer Padmanabhan Krishnamurthy. Krishnamurthy has been assigned the ambitious task of rewriting 98% of the company's legacy code, with a target completion within 24 months. This project highlights Patel's philosophy of fostering innovation by empowering younger employees to challenge existing practices.

Patel believes that "tension is good" within teams, creating productive friction that can lead to better ideas. He advocates for a management style that blends challenging objectives with a foundation of trust. This allows both junior and veteran employees to question current workflows and drive improvements. Krishnamurthy, who joined Cisco after his startup was acquired, was initially in an unstrategic role but proposed this significant code refactoring initiative.

Patel also views younger staff and interns as crucial sources of fresh ideas, acting as "reverse mentors." He shared an anecdote about a Stanford student who, through consistent learning and proactive engagement, secured an internship and later improved a system that experienced staff had found challenging. Patel's approach prioritizes learning from diverse perspectives to avoid stagnation and encourage forward-thinking within the organization.
