Full-Stack Developer with real production experience — I'm co-founder of Belezuura, a beauty & fashion e-commerce in Brazil, where I led the migration from Wix Headless to a 100% Shopify Headless architecture (Next.js 16 · React 19 · TypeScript · Tailwind CSS 4) in 9 months — without a single minute of downtime.
Before tech, I spent almost 8 years managing real-estate registration processes — 500+ cases, hard legal deadlines, zero margin for error. That background is why I translate business requirements directly into software.

};- 🛒 Zero-downtime headless migration: rebuilt a live e-commerce on Shopify Headless — Storefront, Cart & Customer Account APIs with OAuth 2.0 + PKCE, checkout spanning 3 domains (storefront → Shopify → Mercado Pago).
- 📈 Growth engineering: technical SEO (dynamic sitemaps, modular robots, SSR/SSG), LGPD-compliant tracking (Google Consent Mode v2), Meta Pixel + GA4 + Merchant Center — restored paid-media attribution across the full funnel.
- 🚀 Intern → Junior in 25 days at Lesco Revestimentos, after cutting the priority backlog by ~60% in the first month with AI-augmented workflows under strict code review.
- ⚡ +15% performance and −8% load time refactoring Vue.js/Quasar apps; +40% mobile usability and +35% organic indexing on WCAG-compliant freelance work.
- 🏥 E-ReceitaSUS v1.1.0: my own open-source digital prescription system for Brazil's public health system — Flutter app + Node.js/TypeScript API, JWT/JWKS auth, Row Level Security, 3 CI/CD pipelines and a documented security audit (LGPD).
