About me
Hi, I’m a Full-stack Developer & Data Architect.
Stop losing 30% of your data to iOS 14. While others use expensive setups, I use Cloudflare Workers for Meta CAPI & GA4 to fix data leaks with near-zero monthly costs.
Expertise:
✅ Meta Pixel & CAPI (iOS 14 Fix)
✅ GTM, GA4, & Google Ads Tracking
✅ DataLayer for Shopify, WP, & Custom Sites
✅ Flutter App & Web Server-Side Tracking
✅ LinkedIn, TikTok, & Pinterest Pixels
My background in Nuxt, Astro, and Flutter ensures tracking never slows your performance. "If it has a button, I can track it." Message me to scale your ROI!
