Back to original languageAbout Arthur
Network, Cybersecurity, and Automation Engineer (NetDevOps), I support companies in transforming their infrastructure to gain efficiency and security.
Having honed my skills in critical environments (notably at Thales on Defense/Aero networks), I am accustomed to balancing high security requirements with the need for automation.
How I can help you:
Automation & Single Source of Truth (SSOT): Deployment, integration, and development of custom plugins for NetBox. Python scripting to automate your inventories and configurations.
Audit and Cybersecurity: Infrastructure audit, system hardening (Linux/Windows), and integration of best practices (Firewalls, VPN, NIS2 compliance).
Network Redesign: Audit of existing datacenters, proposal of modern and secure architectures.
My technical stack:
Network & Security: Cisco, Juniper, Palo Alto, Fortinet, OSPF/BGP, IPS/IDS.
Automation: Python, NetBox, API (REST/XML/JSON), Bash, PowerShell.
Systems: Linux, virtualized environments (VMware, Proxmox).
Let's work together to make your infrastructure a driver, not a bottleneck!

- iAdvizeQA testing - for LLM trainingCONSULTING AND AUDITSSeptember 2024 - July 2025 (10 months)Valence, FranceI was in charge of testing and analyzing the service offered by Iadize, a chatbot deployed on several major e-commerce platforms (Cdiscount, BoboChic…).
- Functional and user journey audit: conducting in-depth tests to understand the bot's operation, evaluate the relevance of redirections to the correct use cases (product search, customer service, order tracking, etc.), and measure the fluidity of the user experience.
- Large-scale conversation analysis: reviewing and processing millions of customer-bot interactions, with the aim of identifying recurring malfunctions, misunderstandings, or friction points in the journeys.
- Reporting and performance monitoring: developing a detailed Excel file to aggregate results, automate chart generation, and ensure version-by-version tracking of the bot's evolution. This reporting provided a clear and measurable view of progress and allowed for precise targeting of critical issues to be corrected.
This mission allowed me to develop a rigorous approach to performance auditing in the field of conversational AI, combining practical testing, massive data analysis, and strategic reporting to improve efficiency and customer satisfaction. - ThalesDjango Automation PlatformCONSULTING AND AUDITSMarch 2023 - June 2023 (3 months)Valence, FranceDevelopment of an automation platform under Django.-Create scripts to perform inventories on network equipment, whether firewalls or switches.-Host, Interconnections, VIP, VLAN, Pool, etc...
