Summary
Harsh Shah is a Principal Software Engineer in San Francisco with 11 years of experience building scalable, payment- and commerce-focused systems at companies like Roblox, Cash App, Square, and Uber. He combines product-minded engineering with technical leadership—re-architecting offers platforms, leading cross-organizational integration of payment-agnostic offers, and building canonical business identity resolution used across multiple Block products. His work on customer deduplication and Buyer ID integrations has cleaned millions of profiles and enabled enterprise-grade merchant workflows. Comfortable across the stack and data-driven from an earlier data science background, he pairs rigorous MS-level CS training with hands-on delivery in distributed systems and real-time transaction flows. An operator who bridges product, legal, and ops, he’s as focused on measurable business outcomes (e.g., an 18% onboarding lift) as on system reliability and developer ergonomics.
