NELSON PUGET / SPUNTERIA

IT operations · infrastructure · automation · security practice

Reliable systems, clear documentation, and a way back.

IT operations professional based in Geneva, with a foundation in endpoint and identity administration, Microsoft 365, Intune, PowerShell and selected server-management responsibilities. Personal, non-production practice extends into Linux, Proxmox VE, LXC, Docker, automation, backup and recovery, and authorised security labs.

Nelson Puget publishes personal technical notes on agentic workflows, infrastructure, and authorised security practice.

Old-world attention for new intelligence. Clear scope, written steps, and human judgment still matter.

Work

Selected work

Personal studies of systems and practices in progress.

Personal Infrastructure Lab

A personal, non-production lab spanning Linux, Proxmox VE, LXC, and Docker — used to practice service deployment, backup and recovery, and infrastructure documentation outside of any employer or client environment.

Automation & Systems Workflows

Personal automation and scripting practice using Python, Bash, and Git — building repeatable workflows and documentation habits with human-controlled approval, not autonomous systems.

Authorised Security Learning Lab

Structured security learning through Hack The Box Academy and other authorised lab environments, currently covering introductory penetration testing and AI red-team concepts. All exercises remain separate from employer, client and production systems.

Physical Intelligence

Learning electronics, robotics, 3D printing, and practical security gadget-making — one documented prototype at a time.

Tools and practice

Tools and practice

A concise working vocabulary, grouped by the practice it supports.

Operations

Microsoft 365, Active Directory, Google Workspace, Intune/MDM, Apple Business Manager, PowerShell, endpoint lifecycle and selected server-management responsibilities.

Infrastructure practice & DevOps learning

Linux, Proxmox VE, LXC, Docker, Python, Bash, Git, backup and recovery testing. Current study includes CI/CD concepts, Kubernetes, Azure DevOps, Git-based runners and Terraform.

Security learning

Hack The Box Academy and other authorised labs, including Introduction to Penetration Testing and the AI Red Teamer Path — both in progress.

Operating code

How I actually work

The habits behind everything I build.

  1. 01

    Start with the real problem

    Specific problem · useful outcome · build what helps

  2. 02

    Make the system understandable

    Clear instructions · plain language · understand the field’s language

  3. 03

    Automate repeatable work

    Clear workflow · human-controlled automation · approval stays human

  4. 04

    Document changes and leave a way back

    Evidence · backup · rollback

Learning

Current learning

Active study and personal practice, kept within authorised and non-production environments.

In progress

Introduction to Penetration Testing

Hack The Box Academy learning path covering foundational penetration-testing concepts and authorised lab practice.

In progress

AI Red Teamer Path

Hack The Box Academy study focused on adversarial testing and security considerations for AI systems.

Personal practice

Infrastructure and Automation Practice

Continuing personal work with Linux, Proxmox VE, containers, Python, Bash, Git, backup and recovery, and documented operational workflows.

Photography, physical making, and outdoor practice are part of the same routine: pay attention, work with what is there, and adjust when conditions change.
