About

Behind Manaray.

I'm Rayane Declercq, Analytics Engineer. I built Manaray on one conviction: you decide better on data you understand.

My path

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.

My values

01

Reliability

Tested data, traceable calculations, figures that reconcile to the decimal. Trust comes from accuracy.

02

Continuous improvement

I start from what exists and refine it, version after version, until the tool gets out of the way.

03

Care and Clarity

A well-built model, readable code, a clear report: I care for the form at every step, because it carries the substance.

04

Transmission and Longevity

Documented tools, trained teams: what I build is made to last.
