At HIKE & FOXTER, I designed server-side tracking for a multi-market eCommerce, consolidating Google Ads conversion and remarketing tags and deploying Meta CAPI and TikTok Events API.

I audited the consent model and blocked publication when I found personal data being sent to advertising platforms without valid consent. I also led a GTM container migration for a hotel distribution provider and resolved a long-standing GA4 discrepancy.

As a freelance Data Analyst, I built interactive Power BI and Looker Studio dashboards, configured Google Tag Manager and GA4, and helped clients improve conversion tracking and campaign segmentation.

Before that, at Marketing Pixels Web, I designed WordPress sites, landing pages, and online stores using tools including Elementor, Divi, and WooCommerce. I also worked on UX/UI and website optimization.
