Back to original languageAbout Schuller
After several years of apprenticeship and then working as an IT Manager and Cybersecurity Referent, I decided to go freelance: a new challenge, with the desire to bring my knowledge to help you with your various security and infrastructure issues.
I managed an ISO 27001 compliance project from end to end (risk analysis, ISPS, audit preparation), managed Windows/Linux infrastructures on a daily basis, and I also develop in both front-end and back-end when a project requires it.
I also trained in AI tools applied to development and automation (Claude Code in particular), which allows me to produce faster without sacrificing quality. Scripts, documentation, and audit reports are produced in less time, at a price I can keep affordable.
What I offer:
Security audit and risk analysis, with a concrete action plan
ISO 27001 / GDPR compliance (ISPS, risk mapping, audit preparation)
Hardening of Windows/Linux systems, access management, supervision (Zabbix, Centreon, Elastic, CrowdStrike)
Backups, DRP/BCP, virtualized infrastructures (VMware, Proxmox, Docker), cloud (Azure, M365)
Front-end and back-end development for your internal tools and dashboards
Python/Bash/PowerShell automation and integration of AI workflows to reduce manual tasks and accelerate delivery
