Justin Chapman is a software engineer with 12 years of experience building scalable backend and infrastructure systems, currently driving engineering work at Anuvi from Philadelphia. He spent two years at Instagram/Meta focusing on Feed and Explore backends—working on in-feed recommendations, caching infrastructure, and the "why you’re seeing this post" logic—bringing production-grade recommender and low-latency system experience. Prior roles include leadership and founder positions (CTO/VP of Engineering at Event Nation, co-founder of Thrive Commerce) where he scaled web and mobile platforms using Ruby on Rails, AWS, Redis, Postgres, and observability tooling. He has a track record of shipping product-facing systems for high-traffic consumer and e-commerce customers and has experience bridging hands-on engineering with technical leadership. Unusually for an engineer at his level, he also has a creative background as a record producer/songwriter, demonstrating cross-disciplinary product sensibility and collaboration. Justin combines startup grit with enterprise-scale system design, making him effective at both building features and hardening infrastructure.
