https://www.lucavallin.com/blog/tags/ebpf Platform Engineer at Xebia, focused on AI platform engineering - the infrastructure behind reliable, observable, scalable AI and cloud-native workloads. I work primarily in Go and Google Cloud, with deep experience in Kubernetes, containers, and end-to-end observability - and a strong interest in networking and lower-level systems work in Rust. My current focus is the platform layer beneath AI: inference serving infrastructure on Kubernetes, AI gateway and MCP connectivity, agentic workload orchestration, and end-to-end observability for GenAI systems. My broader experience is full-stack: strong on backend, with solid frontend and mobile knowledge. I contribute to open source, write on my blog, and pick up the occasional talk, training, or meetup when something interesting comes up. I'm a Google Developer Expert (GDE) and a CNCF Ambassador. For a deeper dive, see my blog. If you're new to open source, check out Verto.sh. For mentorship, I'm on Mentorcruise. Outside of work, activities like photography, motorcycling, playing a handpan and cleaning litterboxes keep me occupied 🐈. en-us Luca Cavallin Luca Cavallin Thu, 18 Sep 2025 00:00:00 GMT https://www.lucavallin.com/blog/a-tour-of-ebpf-in-the-linux-kernel-observability-security-and-networking https://www.lucavallin.com/blog/a-tour-of-ebpf-in-the-linux-kernel-observability-security-and-networking eBPF lets you run small, verified programs inside the Linux kernel, enabling fast observability, security, and networking without changing application code. This practical tour explains why eBPF matters now, how programs are compiled, verified, JITed, and attached to events, and how maps and ring-3 buffers move data. You'll leave with simple demos and a clear mental model to start experimenting. Thu, 18 Sep 2025 00:00:00 GMT Luca Cavallin ebpflinuxobservabilitysecuritynetworking
