I'm a full-stack developer based in Brazil with 5 years of professional development experience, freelancing since 2023. I build responsive websites, troubleshoot web applications, and connect business tools through APIs and automation.
My main technologies are React, TypeScript, JavaScript, C#/.NET, and Node.js. My work includes ecommerce storefronts, product catalogs, CRM connections, dashboards, and backend integrations.
I can help with React websites and responsive landing pages, web application and API bug fixes, REST API integrations and webhooks, product catalogue workflows, business automation, deployment troubleshooting, and application maintenance.
Selected work:
- Lembre-se 3D: React product catalogue with filters, search and a guided quote-request journey. https://lembrese3d-catalogo.netlify.app/
- Lado Oeste: Interactive React storefront with showroom hotspots, product variants, a persistent shopping bag and CRM/catalogue integration. https://ladooeste.com.br/catalogo
- Duque Colecoes: Collectibles storefront and Google Merchant catalogue synchronization, including product mapping and scheduled reconciliation. https://duquecolecoes.com/
I prefer a clearly defined first milestone with agreed deliverables and practical verification. Weekly availability and start date can be agreed for each project. Portuguese: native. English: conversational.
