An accomplished software engineer, I have over fifteen years of experience in both development and operations. Well-versed in multiple programming languages, tools and technologies, I'm also a seasoned technical leader and mentor. I'm drawn to roles offering challenging and varied problems as part of a talented and close-knit team. Organisations building open-source software or serving the public interest are especially attractive.

Skills

  • Pragmatic approach to complex problems, from tactical short-term goals to long-term strategic vision
  • Experienced in leading teams, acting as technical referent, mentoring other engineers
  • Effective at helping teams plan and prioritise work, negotiating roadmaps with stakeholders
  • Track record of advancing code and infrastructure quality, performance and maintainability
  • Dedicated to automating time-consuming and error-prone tasks

Experience

Cisco MerakiRemote, Australia
Principal Engineer - SREFebruary 2023 to June 2025
  • Acted as the technical advisor for Platform Engineering, a grouping of 7 teams and 35 engineers, by building a shared vision, advising managers, unblocking projects, initiating workgroups, promoting cross-collaboration.
  • Mentored several Technical Leaders, with weekly one-on-ones to discuss technical challenges, career aspirations and leadership development.
  • Continued to help lead the monolith transition into Kubernetes, by organising work, writing design docs, contributing code, reviewing solutions, giving progress demos to stakeholders.
Senior Technical Leader - SREMay 2021 to February 2023
  • Continued to lead the Kubernetes implementation. Grew it to over 40 clusters worldwide, including AWS China, and FedRAMP-certified clusters. Hired and trained a team to take over this platform.
  • Identified a memory leak in the Linux kernel as the source of server crashes using bpftrace and the crash kernel debugger. Implemented a remediation of last resort as a kernel module, which over 18 months mitigated over 25,000 leaks, avoiding thousands of server crashes.
  • Kick-started a multi-year initiative to migrate our monolith from bare-metal into Kubernetes, using custom tools and services.
Technical Leader - SREMarch 2019 to May 2021
  • After extensive analysis of the container orchestration landscape, led the design and implementation of Meraki's EKS-based Kubernetes platform, provisioned using Terraform and Helm. It included Grafana SLO/SLI dashboards, Fluentd/Kinesis logging pipeline, Okta authentication, Statsd/Prometheus metrics collection, Gitlab CI deployments, Kyverno admission control, strict default Pod Security Policies and Network Policies.
  • Designed and implemented a Haproxy-based on-prem proxy infrastructure, for exposing customer-facing services running in EKS on IP ranges owned by Meraki. At peak, it was handling 3 million concurrent connections.
  • On-call in a follow-the-sun schedule. Triaged PagerDuty alerts, investigated root-causes, deployed remediations or rollbacks, ran post-mortems.
VMTechSydney, Australia
DevOps EngineerAugust 2018 to February 2019

Publications

Cardiac Interventional Guidance using Multimodal Data Processing and Visualisation: medInria as an Interoperability PlatformMidas Journal2012
Authors: F. Vichot, H. Cochet, B. Bleuzé, N. Toussaint, P. Jaïs, M. Sermesant
MedInria is a medical imaging application developed at Inria, which aims to provide clinicians with state-of-the-art algorithms for processing and visualising their images. In this article, we focus on its use in pre-surgery preparation for cardiac interventions, and the difficulties arising from the lack of standardisation of certain data formats and visualisation conventions.
IpMorph: fingerprinting spoofing unificationJournal in computer virology 6, no. 42010
Authors: G. Prigent, F. Vichot, F. Harrouet
Nowadays, there are a variety of tools for easily identifying the TCP/IP stack's fingerprint of a target machine. IpMorph allows this fingerprint to be concealed, and even mimicks the fingerprint of a chosen TCP/IP stack. This is done through live session tracking and packet rewriting. Its effectiveness against tools such as Nmap, Xprobe2, Ring2, SinFP and p0f is also detailed.
