Rockstar🎓
Top SchoolPeijen Lin is a software engineering manager with 13 years of experience building scalable cloud-native systems and leading cross-functional teams from prototype to production. Currently at CoStar Group after managing data visualization and large-scale mapping systems at Roofstock, he excels at turning complex datasets into usable products (e.g., rendering up to 100 million SFR properties and migrating PostgreSQL to Snowflake). He was a founding member of Kaggle’s Datasets team, designing a metadata model and access layer that now supports hundreds of thousands of versions and billions of monthly reads and writes. Comfortable across the stack, Peijen brings deep distributed-systems, cloud (Azure/GCP), and connected-device experience combined with hands-on mentorship and hiring expertise. He has a track record of accelerating release cadences and driving cross-team collaboration to deliver production-grade features. Based in Irvine, CA, he pairs CMU-trained engineering rigor with an entrepreneur’s curiosity — a former president of a side venture who still daydreams about building the next big company.
