Yalei Wang's past jobs
Built and led a cross-disciplinary (development, testing, SRE, product management and sales) team of 50 members. Our team built a smart monitoring system for private data centers and online services for enterprises. The system collected metrics, logs, and events from various software applications, services, operating systems, network devices, and hardware. The product provided a cross-system, aggregated view, plus had analytics capabilities of metrics, logs, and events. It sent alerts via emails, phone calls, or short messages should any anomaly have been detected manually (human operators) or automatically by algorithms. In addition, I led the development and delivery of a distributed document management system and object store service. It was optimized to store large data and documents as images, 3-D model files, and more. This extensive system supported different types of raw data storage backend (e.g. an in-house built file system-based content store, AWS S3, or Ali OSS, etc.). Additionally, the system supported a flat object storage scheme as well as a hierarchic document/folder structure.
I worked on Twitter’s in-house built large scale, and distributed key-value store Manhattan. Manhattan stores and serves 80% of Twitter's online data. I led the team that delivered secondary-index on No-SQL database, and reliable low-latency cross datacenter replication features. I was in charge of Twitter’s counter cluster, an operational metrics data store. It was the largest cluster in terms of the number of nodes, throughput, and data stored. Additionally, I participated in the delivery of a strong consistency data storage system.
I was in charge of the cross-border shipping platform. I delivered China to the US and Japan to US shipping products. The task of delivering the two products was originally owned by another team, which was not deliverable for two years. My team took over at the last minute and the products were successfully go online within six months of transitioning.
I worked on the game promotion platform. The platform sent game promotions to millions of Zynga’s game players.
My work focused with the online store in the Ads Delivery Engine (Ads Server) group. The product we built was a distributed, low latency in-memory data store and execution platform. It provided data storage and computation for different services in the ad’s delivery pipeline. The tail latency requirement for end-to-end requests in each of these services was in the low teen milliseconds. Before moving to the online store team in the ads group, I worked on the SQL Server BI team and relational engine team.
