Senior🎓
Top SchoolArnaud Gissinger is a Paris-based product engineer and two-time founder with eight years of experience building scalable, user-focused platforms and architecting systems from monoliths to low-latency distributed services. He led engineering and product work at Peach—designing seven products and a streaming platform that reached 500k MAU while keeping global latency under 200ms—and has hands-on experience cutting costs and improving performance at SaaS startups. A 42 Paris alumnus and active contributor to neo4j/graphql, he brings practical backend expertise in query execution, auth rules, and integration testing to complement his product instincts. He also advises and builds AI-first legal and biotech products, demonstrating an ability to translate complex domains into simple, automated user workflows. Non-obvious: he combines founder-level growth hacking (driving multi-million view metrics) with deep systems trade-off thinking, making him equally comfortable shipping features and optimizing infrastructure.
