At bLoja.com.br, I own the multi-tenant SaaS platform end to end, from architecture and development through infrastructure and production releases. I designed its architecture and storefront generation engine for businesses across multiple market segments.

I defined and implemented technical SEO features including sitemap indexes, crawler policies, and structured data to support tenant stores’ discoverability through search engines and AI assistants. I also manage cloud infrastructure and edge configuration using Oracle Cloud, Cloudflare, and Docker.

Previously, I designed and built Mobiauto Sites, a CMS for vehicle dealerships with a vehicle e-commerce module, customer login area, and shopping cart. At EBANX, I developed and maintained financial applications, back-office systems, internal APIs, and integrations for a cross-border payments company.
