Senior🎓
Top SchoolJeffery Do is a Founding AI Engineer and entrepreneur in the San Francisco Bay Area with 11 years of experience building large-scale backend and data systems. He designed and operated high-throughput ETL and streaming pipelines and audience segmentation microservices at PlayStation that handled hundreds of millions of users and materially increased sales across PS4, PS5, and the Webstore. Comfortable across Java, Scala, Kotlin, Python and golang, he combines hands-on engineering with a DevOps mindset—driving Kubernetes migrations, CI/CD automation, observability, and operational runbooks. Jeffery is now applying that product-focused infrastructure experience to founding roles at a stealth AI startup and BitsOf, bringing a pragmatic blend of data engineering, ML-ready tooling, and developer productivity. A natural collaborator and documentarian, he often codified onboarding, created diagnostic tooling, and recorded training materials to scale knowledge across large engineering teams.
