Rockstar🎓
Top SchoolJerry Tan is a software developer with five years’ experience building reliable systems and a strong open-source footprint as a core maintainer of sbt and the Zinc incremental compiler, contributing 100+ merged PRs across Scala tooling. He has a proven knack for diagnosing and resolving subtle, production-impacting build issues—having helped organizations like Morgan Stanley, Typelevel, Akka and Databricks ship complex features and fixes. At Visier and previous co-op roles he delivered performance and security improvements (e.g., reducing page load times by an order of magnitude and cutting Cassandra queries via a Kafka-backed writethrough cache). Comfortable across Scala, Java, and frontend stacks, he combines deep compiler/build-tool expertise with pragmatic product delivery. Based in Langley, BC, he is authorized to work in Canada and the US (TN) and holds a BSc in Mathematics & Computer Science from UBC.
