Summary
🤩
Rockstar🎓
Top SchoolJason Dellaluce is a systems-focused software engineer and former YC founding engineer with a decade of experience building low-level, real-time security and observability infrastructure. He’s a CNCF core maintainer on Falco and has driven kernel- and eBPF-level work across projects like sysdig, improving multi-arch support, performance, and verifier compatibility. Jason combines C/C++ and Go expertise with deep Linux, Kubernetes, and compiler know-how to design portable, stateful detection systems that run from edge to cloud. As a technical lead he cut open-source fork management and feature delivery times by ~90% and architected an all-in-one stream processor for security detections. Early hands-on reverse-engineering (including published 3DS kernel exploits) underpins his pragmatic approach to systems security and observability. Based in San Francisco, he mentors open-source contributors, speaks widely at industry events, and pairs serious engineering with a passion for basketball and cooking.
