About

Eleven years inside one product — and counting.

I'm Vincent — R&D Director at Kizeo, a B2B SaaS for field professionals. I joined when the team was three. We're now fifty-plus, and the product has grown with every architectural decision made along the way.

This blog is where I write down the things that took me a long time to understand: Laravel architecture, multi-tenancy at scale, the tradeoffs that never make it into the documentation.

Tech I reach for

The stack is boring on purpose. Boring means I spend my time solving problems that matter, not keeping up with the framework of the week.

How I write

One post at a time, when something's bothered me long enough to be worth explaining. I don't publish on a schedule — and I don't apologise for weeks of silence. Posts land in English first, French follows when the topic warrants it.

If you want to follow along, the RSS feed is the honest channel. There's also /llms.txt for the crawlers among you.
