Freelancer profile translated to English.
Back to original languageAbout Xavier
Independent senior DevOps/Cloud consultant, I help make platforms simpler, safer, and faster.
Accustomed to multi-cloud and hybrid/on-prem environments, I bring predictability: short framing, prioritized action plan, clear milestones, and direct communication.
On a daily basis, I standardize with IaC (Terraform), industrialize CI/CD, manage containers & orchestration, and design back-end APIs (mainly Python). I apply pragmatic observability and an SRE mindset to measure quality, deadlines, and reliability.
My way of working: transparency, useful documentation (runbooks, reusable templates), and skills transfer to make the team autonomous.
Reliable, discreet, and ethical, I prioritize concrete results over buzzwords: less risk, more value, and a foundation that lasts.
