Ephraim Pei is a senior full-stack software engineer with 11 years of experience building and scaling product-focused systems across finance, media, and cloud platforms. Currently at MongoDB on Growth Platforms, he blends backend expertise (Go, Python, Node, Kafka, Cassandra) with frontend and experimentation tooling to drive user acquisition and onboarding. Previously he led Growth Tech engineering at Capital One Shopping, owning experimentation APIs, high-throughput ingestion pipelines, and fast static marketing experiences while managing cross-functional teams and vendor partnerships. His background spans rapid prototyping and enterprise systems from EY and Accenture to content platforms at VICE and Univision, giving him strong product intuition and operational rigor. Known for hiring and mentoring engineers as much as shipping features, he favors efficient, memory-conscious designs and self-service tooling that empower product and marketing teams.
