My skills
in production

High-availability virtualisation, hybrid identity, cybersecurity and automation: the technologies I run every day on critical infrastructure, and the ones I explore further in my studies and in my home lab.

Infrastructure
foundations

I administer vSphere 7.0 and 8.0 and vSAN clusters stretched across two datacentres, with witness servers. From racking to ESXi provisioning, I handle the full hardware lifecycle. On the systems side, I manage complex Active Directory domains and the governance of the Azure AD / M365 tenant: MFA, conditional access and AD Connect.

Details

Professional
expertise

From datacentres to identities, from threat detection to automation: here, area by area, is what I run every day in production, what I study in depth, and what I build at home in my home lab.

01Infrastructure & security

VMware expertise

Advanced vSphere administration (7.0 & 8.0) and management of clusters stretched across two datacentres (dual-site) for full high availability.

vSAN storage

Configuration, expansion and monitoring of vSAN clusters. Strategic deployment of witness servers for resilient virtualised storage.

Hardware & compute

Full hardware lifecycle: physical installation, racking, structured cabling and software provisioning of ESXi servers.

02Systems & hybrid identity

Active Directory

Management of complex domains, setup of trust relationships and streamlined administration with ADManager Plus.

Azure AD / M365

Full tenant governance, MFA rollout, conditional access policies and identity synchronisation (AD Connect).

Windows services

Command of critical roles (GPO, DFS, DNS, DHCP) and patch management campaigns with WSUS and Ivanti.

03Security & traffic management

Detection & response

Administration of SentinelOne EDR and use of the Sekoia XDR platform for event correlation and incident response.

Vulnerability management

Continuous scanning with Cyberwatch, rigorous tracking of the patch lifecycle and enforcement of hardening standards.

Proxy & reverse proxy

Configuration and updates of Artica Proxy, and administration of F5 BIG-IP (nodes, pools and custom iRules).

04Linux & open source

Server administration

Deployment and hardening of Debian, Ubuntu and Rocky in production environments.

Services & web

Configuration of web servers (Nginx, Apache) and file servers (Samba), with advanced permission management.

Maintenance

Log analysis, repository management and automated system updates. Monitoring with Servicenav / EV Observe.

05Strategic projects & automation

Cloud migration

Technical lead of the SharePoint migration for 1,500 users, including planning, data transfer and change management.

IT system merger

Active contribution to merging the critical infrastructure of the cities of Pierrefitte and Saint-Denis (unified directories and resources).

DevOps & documentation

Resource optimisation with Docker and systematic technical documentation (architecture and operations documents) to keep systems sustainable.

The projects and architectures presented on this site have been anonymised or altered to respect the confidentiality and security policies of partner organisations. No sensitive or critical data is publicly disclosed.

06Academic expertise & engineering

Architecture & hybrid cloud

Design of virtualised environments (vSphere, vSAN, Proxmox) and deployment of multi-cloud architectures (AWS, Azure, GCP). Study of distributed storage (Ceph) and hyperconvergence (Nutanix).

Systems security & resilience

Zero Trust strategies and system hardening (Linux LPIC / Red Hat, Windows Server). Preparing for the Palo Alto (PCNSA) and Juniper (JNCIA) certifications.

Automation & DevOps culture

Industrialisation through Infrastructure as Code (Terraform, Ansible) and container orchestration (Kubernetes, Docker). GitLab CI/CD pipelines.

07Personal & home lab

Hardware

Server architecture & virtualisation

A physical infrastructure built on two Dell PowerEdge servers, with the hypervisor configured to simulate enterprise scenarios (HA, live migration).

Web & access

Web hosting & security

Fully self-hosted portfolio, alexandre-faye.fr, on a dedicated mini PC. LAMP stack management and performance tuning. A personal VPN tunnel secures remote access to my infrastructure and encrypts my browsing traffic.

Media & storage

Streaming & data management

Plex media server with automated library management and hardware transcoding. Persistent data volumes and backup strategies for my critical services.

Services

Containers & orchestration

Deployment and management of a container stack including Wiki.js, Nextcloud (private cloud) and Erugo (secure file transfer).
