Summary
👤
Senior🎓
Top SchoolDavid Reiman is a Staff Engineer in Oakland with eight years of software experience who combines deep ecosystem knowledge with product-focused architecture to connect the right people and solve high-impact problems. At Credit Karma he architected major consumer-facing financial features—TurboTax Refund Advance and Instant Karma debit rewards—that together unlocked over $1.75 billion for users and generated hundreds of millions in incremental revenue, while also leading front-end tax teams that enabled millions to file for free. His background blends rigorous scientific thinking (BS in Physics from Yale) and research-oriented deep learning work with hands-on engineering across TypeScript/React, Scala/Java, GraphQL, and cloud-native platforms. A former teacher and admissions officer, he brings clear communication and coaching instincts to technical leadership, plus an eye for features that scale both product and social impact. Notably, he balances technical stewardship with company culture—earning multiple awards for helpfulness and innovation—and still finds time to captain charity runs and perform in a company band.
