Instagram Reels Creation Team:
• Led a 13-person cross-functional workstream (8 engineers, 5 XFN) to architect a scalable NUX manager. Successfully drove audio adoption for Photos & Carousels, resulting in an incremental 400K+ daily posts from teen creators and 770K+ daily posts across the general population.
• Drove $1.8M in annual CPU cost savings by auditing and eliminating over-fetched data across 10+ high-volume Instagram Reels backend APIs, optimizing server resource utilization at scale.
• Led 0-to-1 design and launch of the Offline Sync Agent. Architected a disk-backed mobile cache with custom eviction logic and a GraphQL-based batching infra to recover user engagement actions during poor network conditions; Engineered client-side rate-limiting heuristics to mitigate a 3% spike in engagement-abuse. Recovered +218,000 likes, +163,000 comments, and 1.1 million user posts daily.
