Sam Sampey is a software engineer in San Francisco with 11 years of hands-on experience building reliable back-end systems and developer-facing tooling. Currently at Google after an internship there, he brings practical production experience from internships at Amazon and the Chicago Board of Trade where he shipped automated testing infrastructure, UI improvements, and an algorithmic trading system. He contributes to Apache Beam—improving Java SDK error handling, deduplicating core logic, and enhancing timers—demonstrating a focus on robustness in distributed data processing. A Carnegie Mellon CS graduate, Sam blends systems-level thinking with pragmatic engineering: reducing test-generation latency by over 50% at Amazon and delivering measurable trading results in simulation. He excels at turning messy edge cases into clearer, maintainable implementations and enjoys tackling deceptively small changes that have outsized impact on reliability.
