lucavallinHello,
Luca here.
I build the platform layer beneath AI — Go, Google Cloud and Kubernetes by day. The rest of this place is everything else I get up to: writing, open source, motorcycle videos, photography, a handpan, and two cats.
that's me ☺

AI Engineering for Developers
A tour through AI engineering for developers who already know how to ship software. Fourteen chapters, no LinkedIn voice, no slow warm-up. We will go from 'what is a foundation model' to 'how do you run agents in production on Google Cloud' without skipping the parts that matter.

Platform Engineering End-to-End
Platform engineering is more than DevOps with a portal. This post walks the full arc of the discipline end to end: why platforms exist, how to build and operate them, how to manage the messy stakeholder politics, and what success actually looks like. Grounded in Fournier and Nowland's book and a few years of doing this on real systems.
Google Cloud Networking 101: The Comprehensive TLDR
A comprehensive but quick walkthrough of everything you need to know about GCP networking: VPCs, subnets, routing, firewalls, Shared VPC, GKE networking, load balancing, Cloud NAT, hybrid connectivity, VPC Service Controls, DNS, packet inspection, and how to operate all of it. Written for engineers who need a solid mental model in 15 minutes.
Containers Are Not Automatically Secure
Containers changed how we package and ship software, but they did not rewrite the basic security rules. Trust boundaries, privilege, and attack surface are all still there. That was probably the main thing I learned while digging into container security, partly from Liz Rice's Container Security and partly from spending time with the Linux pieces underneath.
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.

Qroda turns motorcycle and bicycle rides into striking map posters — GPS track, speed, lean angle and weather, captured on the road. Private by design: no accounts, no servers, everything stays on your iPhone. It lives at qroda.lucavallin.com.
