Reliability
Tested data, traceable calculations, figures that reconcile to the decimal. Trust comes from accuracy.
I'm Rayane Declercq, Analytics Engineer. I built Manaray on one conviction: you decide better on data you understand.

From L'Oréal to Smallable, through Chanel, Guerlain, Withings and Mytraffic: years of data work for retail and luxury, in environments where every decision puts margin on the line.
My approach: start from what exists and refine it. I adapt to the environments in place, and I push to rework what deserves it, bringing in new tools when they improve the teams' day-to-day. AI takes its place there naturally, no more, no less.
Independent today, I bring that standard to houses and companies that want to decide on solid ground and embed that data culture in their teams for the long run.
Tested data, traceable calculations, figures that reconcile to the decimal. Trust comes from accuracy.
I start from what exists and refine it, version after version, until the tool gets out of the way.
A well-built model, readable code, a clear report: I care for the form at every step, because it carries the substance.
Documented tools, trained teams: what I build is made to last.
