At Preco Local, I designed and built the core API from scratch in Node.js and TypeScript, integrating catalog, pricing, search, and geolocation data. I also developed the cross-platform mobile app and published it on Google Play Store and Apple App Store.
At Sky Store, I designed and maintained Node.js and Postgres backend services. I implemented RabbitMQ message-queue patterns and Redis caching for asynchronous processing flows.
At Rituais de Axé, I designed payment architecture for instant Pix flows and automatic enrollment after payment confirmation. I built backend services for purchase, enrollment, authentication, and content access.
At a confidential company in data and document search, I built Java search services and contributed to moving a legacy monolith into event-driven microservices. I modernized indexing and query flows, reducing complex search latency from about 1 minute to 5 seconds. I also built ViaNova, an account, identity, and billing hub, and Naia, a multi-tenant messaging platform; both ran in production and were open-sourced after shutdown.
