Summary
👤
Senior🎓
Top SchoolMatthew Jeng is a backend and full-stack software engineer with eight years of experience building data-driven, production systems at scale, currently on Facebook's engineering team in San Francisco. He is fluent in Java, Go, Python, C, and JavaScript and has hands-on experience with Postgres, Docker, and observability/debugging tools, often tackling both performance and correctness challenges. His background includes optimizing large batch jobs with Spark, generalizing image enhancement pipelines and A/B testing at Facebook Marketplace, and building real-time dashboards with Go and React. A former UC Berkeley CS instructor, he brings strong mentorship and teaching chops—having led labs, guest-lectured on Scheme, and TA’d an advanced security course—so he pairs technical depth with clear communication. Notably, he has repeatedly moved projects end-to-end from architecture and onboarding to deployment and metrics, reflecting a bias for ownership and measurable impact.
