• I lead the Rewards+ teams which is part of the bigger Walmart+ organization. With the mission of retention, and directly helping acquisition, this team crosses boundaries with Search, Promotions, Benefits, and other critical teams inside Walmart.
• I was directly involved in leading a newly formed team, installing optimal processes, and rituals, and investing in team health and culture. I spearheaded the collaboration between Product and Engineering to strengthen the relationships to maximize business value by betting on both short and long-term initiatives. Scaled the team and focused on delivering by driving big efforts like opening up Rewards to all customers(not just members) thus executing directly on Walmart's core missions.
