What I'm looking for

I'm available for in-person, hybrid, or remote opportunities.

At Engenharia de Ecommerce, I contributed to the development and evolution of a Business Intelligence platform for e-commerce, with sales, inventory, catalog, and financial indicators. I worked on REST APIs and external marketplace integrations, including webhooks, retries, idempotency, backfills, and data reconciliation.

I also worked on business rules for revenue, margins, taxes, promotions, coupons, costs, shipping, inventory, and sales. My work included migrations and automated tests, as well as authentication, authorization, and rate limiting.

At MundoFit, I developed a mobile app for student management, with workout, nutrition, authentication, and progress-tracking flows. I used React Native on the frontend and integrated REST APIs with Node.js and Firebase.
