About Mickaël

When the product accelerates, the platform must remain manageable.
That's where I come in.

DevOps & Platform Engineer focused on Developer Experience, I support tech teams when complexity starts to set in:
implicit dependencies, diverging environments, cobbled-together automations, fragile pipelines.

I start by understanding how the system actually works.
I identify the weak points, then I simplify and stabilize what needs to be.

My goal: a platform that is readable, reproducible, and truly serves developers.


📌 I intervene:

• As a freelance DevOps / Platform Engineer
• For audits to provide a clear diagnosis and define a structuring roadmap

The audit can then lead to targeted intervention or light support depending on the context.

Large companies, scale-ups, tech SMEs:
if your product is accelerating, your platform must remain under control.

If this is a topic for you, I reserve a few slots per month for an Express Platform Review: 30 minutes to look together at where things are getting stuck.
