Top SchoolAngela Mao is a Staff Software Engineer and tech lead with a decade of experience building high-impact Android and full-stack products, most recently at Meta where she led cross-functional launches across Instagram and Threads used by hundreds of millions. She excels in 0→1 environments, having delivered a launch-ready standalone Android app in seven weeks and helped found IG Japan Labs while scaling teams through hiring and onboarding. Her work spans consumer-facing features (Shopping in Reels, Live Shopping, profile/highlights) and critical infra like cross-team analytics and shared Android stability, blending product intuition with engineering rigor.
