Data Engineer · Automation & Acquisition (Google Ads, Shopping, Websites)

Data Engineer at Hexafret (SNCF subsidiary), Master's in Data Engineering at Paris Ynov Campus.

Three things I do:

Data & reporting. Your revenue, costs, stock and margins surfaced in a Power BI dashboard you can walk into a board meeting with. VBA and Python automation to kill your Monday-morning Excel reporting. Clean SQL, Power Query, row-level security when needed.

Websites. Showcase sites, portfolios, e-commerce. Responsive, proper Google Analytics tracking, e-commerce tagging that actually fires Add to Cart and Purchase events. No pretty sites with broken measurement underneath.

Google Ads, Shopping and Merchant Center. Product feed configured and validated (no more GMC rejections), Ads and Shopping campaigns launched and managed, ROAS monitored, audience and creative testing. You know exactly what each euro brings in.

How it works. 20-minute video kick-off to align on the business goal, milestone delivery, Git-versioned code, Notion documentation, Loom handover video. Training included on Gold, 30-day support on Diamond.

What I don't do: micro-services at 5 euros. Gold starts at €450, Diamond at €1,500.

Response under 2 hours on business days. NDA on request. Native French, professional English.
