Top SchoolJohn Grossmann is a Senior Software Engineer with 11 years of experience building secure, performant systems for both startups and large tech firms, currently focused on ad infrastructure at Netflix after leading Amazon Ads inventory initiatives. He combines deep systems and security expertise—having designed PKI, custom TLS handshakes, and privacy-preserving overlay networking at All Purpose Networks—with product-facing work on network management and GUIs. At Amazon he acted as a tech lead unifying cross-team efforts to optimize ad inventory and improve DSP customer experiences, translating complex distributed systems constraints into measurable business outcomes. Comfortable across the full stack, John pairs rigorous engineering (Columbia MS in Computer Engineering, dual BA in Physics and CS from Colgate) with hands-on leadership and an inclination for novel protocol design that reduces attack surface while enabling seamless network handovers.
