Christopher Rrapi

Software Engineer

San Francisco Bay Area

I work on backend infrastructure, distributed systems, and AI/ML applications. I interned twice at Google, on Cloud Infrastructure and on YouTube Ads. Before that I built enterprise tooling at Verizon and studied quantitative problem solving at Jane Street. I graduated from UMass Amherst with a BS in Computer Science in December 2025.
