Kevin Santana

I'm a Data & BI Analyst based in Paris with 2+ years of experience turning large, messy datasets into decisions businesses actually act on, most recently at EssilorLuxottica.

My strongest work: I built a Python ETL pipeline processing 20M+ rows from SAP BusinessObjects, segmented into 18 country-governed datasets, to power a retail reporting product used across a 60K+ point-of-sale network (+15% productivity). On top of that, I designed a Power BI galaxy-schema model from scratch, including a client-scoring KPI that grew the network's top-performing stores from 105 to 135 and flagged underperforming accounts for reactivation. Root-cause analysis from that same model linked a segment of underperformance to product pricing, findings that contributed to a company-wide buy-back strategy. I've also built cross-functional data tools (Finance, Logistics, Customer DW) for returns/risk monitoring, and run impact studies that led teams to redesign go-to-market strategies when results fell short of target.

Toolkit: Power BI (DAX, data modeling), Python (ETL, automation), Excel advanced, SAP BusinessObjects, VBA. I'm actively deepening SQL through hands-on projects (StrataScratch, a public GitHub build in progress) rather than claiming it as a finished skill.

I care most about the "why" behind the numbers, not just the dashboard. What I'm looking for next: a Data/BI Analyst role at a fintech or fast-scaling startup where I can own analysis end to end and see it directly shape product or commercial decisions. Native Spanish, fluent English, working French (B2, actively improving).
