Jonathan Mertens, infra consultant.
Fifteen years designing, maintaining and repairing infrastructures. Now independent, between Belgium and France.
Why independent.
Too often, infra gets built fast and the SME ends up with technical debt it can't carry. As an independent, I pick my clients, I know their infra by heart, and I'm directly reachable. One contact, simple, direct.
Why SMEs.
An SME has a tight IT budget, little or no internal tech team, and needs infrastructure that just works. That's exactly what I do. I don't want to deal with big-company politics; I want my client's business to be running on Monday morning, without them having to worry about it.
Why BE + FR.
I grew up in Belgium and worked there for 10 years. Both markets look alike on the SME side, but each has its own specifics (GDPR, hosting, local regulations) that I know. I invoice from France through my micro-entreprise, including for Belgian clients: one status, one invoice, no admin headache for you.
