Where Infrastructure
Meets Intelligence

Bridging the gap between physical infrastructure and software-defined optimization at planetary scale.

Digital Twins & AI

Architecting enterprise-wide Digital Twin platforms that model physical infrastructure across Space, Power, Cooling, and Network, enabling AI-driven predictions and autonomous operations.

Zero-Touch Automation

Pioneered the paradigm shift from manual SME operations to fully intent-driven, closed-loop network management systems at Google-scale, setting new industry standards.

Global Network Architecture

Deep expertise in designing and operating IP backbones, from pan-European core networks to hyperscale production infrastructure serving billions of users.

Reliability

Created the "Fragility Index", a quantitative approach to preventive maintenance that identifies and resolves latent risks before they cause incidents, shifting operations from reactive firefighting to fix-before-break.

Organizational Transformation

Proven track record guiding large-scale engineering organizations through radical shifts, from legacy operations to modern, software-defined workflows.

Strategic Leadership

Engineering excellence and rigor at Google scale. C-level advisory, technical vision-setting, and building high-performing distributed teams that launch, iterate, and operate planet-scale systems across continents.

How I Think

Four principles shaped across nearly three decades of building and operating global infrastructure. Read the Automation Ladder →

01

Infrastructure is a software problem

Every cable, router, and data center is a node in a system that can be modeled, reasoned about, and orchestrated through code. The moment you see infrastructure through the lens of software, you unlock automation at every layer. Read the essay →

02

Fix before break

Reactive operations are a tax on scale. Quantify latent risk, surface hidden fragility, and resolve it before it becomes an incident. Preventive maintenance is not a cost center, it is the foundation of reliability.

03

Automate the automator

The goal is not to build tools that help humans operate networks. The goal is to remove humans from daily operations entirely. Zero Touch means the system operates itself, and engineers focus on making the system smarter.

04

Model the domain, the code follows

Start with entities, relationships, and constraints, not with code. A well-modeled domain becomes the single source of truth that drives configuration, validation, workflows, and health assessment. Get the model right and the system designs itself. Read the essay →

Closed-Loop Control

Infrastructure as a control system. Define intent, strategize the path, execute, observe the outcome, assess the drift, and feed it back. The pattern behind Zero Touch Networks and Digital Twins. Explore the architecture portfolio →

CLOSED LOOP CONTINUOUS CONVERGENCE DRIFT DETECTED → RE-CONVERGE 01 Intent What should be 02 Strategize How to get there 03 Execute Execute safely 04 Observe What actually is 05 Assess Measure the gap
A closed-loop control system where infrastructure continuously converges toward its intended state. Each cycle refines the strategy, and the loop never stops.

The Journey

Originally from France, dual French-Australian citizen. From early Internet infrastructure in Amsterdam to Sydney, the Bay Area, and Zurich, building and automating the global distributed systems that power the modern Internet. View the global map →

Network Health Lead → Head of Global Network Automation
16 years transforming Google's production network. Led the "Zero Touch" initiative that removed humans from daily network operations. Managed global teams building Go-based microservices for massive-scale configuration and workflows orchestration. Created the Network Fragility Index to prevent the preventable.
Network Health · TL/M (2021 – 2023)
Created the Network Fragility Index, a preventive maintenance framework that quantifies latent risk to fix systems before they break. A metric-driven approach to proactively surface and resolve hidden fragility before it escalates into incidents.
Network Lifecycle Automation · TL/M (2015 – 2021)
Led B2 Network Lifecycle Automation, five pillars covering the full lifecycle of Google's production network infrastructure:
Modeling Entities, relationships, attributes, validation Configuration Routers, optical nodes, switches, services Workflows Add/Move/Remove/ZTP/QA/Repair Network Safety Pre-check & just-in-time safety checks Network Health Proactive health assessment & remediation
Technology & Architecture
Go as the language of choice since ~2015, deprecating Python in production. Everything built as microservices using Protocol Buffers and Stubby (ancestor of gRPC), deployed on Borg. Users were deployment and site engineers bringing new capacity into production autonomously through a web UI.
Senior Network Engineer → SRE Staff Engineer (2007 – 2015)
Led the software automation function area for Google Global Networking. Built the foundational API ecosystem, observability platform, and workflow automation systems for Google's production network, replacing text-based MOPs with guided workflows executable by non-SMEs.
