Summary
🤩
Rockstar🎓
Top SchoolFrançois Garillot is a Senior Staff Engineer with 15+ years building high-throughput distributed systems, streaming analytics, and cryptographic primitives across startups and major labs. He has deep expertise in Scala, Spark Streaming (Databricks/O'Reilly certified and contributor), Rust-based crypto, and blockchain core logic—contributions include work on Curve25519 implementations and consensus/storage for Sui, Flow, Aptos and Diem. His background spans academia (PhD-level work on type systems with Martin Odersky) to production leadership roles (CTO/Head of Engineering) where he operationalized near-real-time mobility analytics and ad-auction models at internet scale. François pairs research-grade rigor with pragmatic engineering: performance-driven refactors, serialization and typed-DB improvements, and property-based testing across multiple repos. He’s equally comfortable designing scalable algorithms for millions of users and implementing low-level cryptography and ZK/SNARK plumbing. Based in Montreal, he blends systems-level thinking with hands-on contributions to high-profile open-source projects.
