Summary
🤩
Rockstar🎓
Top SchoolSimone Mainardi is a Principal Network Security Engineer based in Dublin with 12 years of hands-on experience designing high-performance, secure network visibility and traffic analysis systems. Now at Salesforce after leading network security engineering, he previously architected and managed ntopng and nEdge projects, delivering up to 20x performance gains and enabling deployments across fleets of vessels and yachts. He combines deep C/C++ backend skills, eBPF/netlink agent work, and large-scale data pipeline experience (Kafka, ClickHouse, MySQL) to solve real-world observability and security problems. An active open-source contributor to ntopng and nDPI, he has improved protocol detection, alerting and database integrations for widely used network monitoring tools. He also brings academic rigor—a PhD in Information Engineering—and a track record of securing software via audits and delivering funded European research projects. Less obvious: he pairs low-level packet-inspection expertise with production-grade telemetry and customer-facing deployments for Fortune 500 and military clients.
