Notable impacts include stabilizing a business-threatening database outage, championing a BFF that cut P75 load times by 100ms+, and introducing Backstage to halve new-project setup time. At Cash App he led incremental migrations for a massive codebase and pioneered practices to improve AI-assisted development quality. He focuses equally on engineering craft and people growth, having mentored engineers into senior and staff roles and led hiring across multiple teams.
