Vector is LinkedIn’s media processing and serving infrastructure. Vector handles creation, processing, storing, and presentation of all media content that includes images, videos, documents, audio and related metadata. Vector provides both internal and member-facing APIs, powering use cases like LinkedIn profile images, feed videos, messaging attachments, LinkedIn Live and more. Over 100M+ images and videos are processed per day and served at more than a million QPS at peak.
I designed and built an e2e performance testing and media validation platform, responsible for monitoring the data pipeline's health and ensuring that media assets are processed timely and correctly. I also helped with the full launch of the infrastructure taking traffic for all of LinkedIn's media assets, by assisting with building the business logic and handling unexpected issues.
