Senior🎓
Top SchoolEric Jung is a seasoned Staff Software Engineer with 16+ years building and modernizing large-scale, high-throughput systems across Java, Node, Python, C/C++, C#, and JavaScript. He combines hands-on full-stack development and technical leadership—driving migrations from Redshift to Databricks, modernizing Java/Spring stacks, and designing Kafka Streams event-driven pipelines at scale. Founder of FoxyProxy, Eric maintains an open-source browser extension recommended by AWS and used by hundreds of thousands of users, and his name is engraved on the Mozilla Monument for contributions to Firefox. A published author of an 850-page professional Java reference, he’s been quoted in Forbes and CNET and has repeatedly delivered secure, test-covered services in regulated environments. Comfortable operating from product to infrastructure, he also mentors engineers and enforces code quality with tooling like SonarQube and CheckStyle. Rarely content to stay in one layer, he still dives into low-level debugging and cross-platform builds—from browser extensions to TB-scale ETL pipelines.
