At SmartNew System, I develop and maintain REST APIs and back-end services with NestJS, Node.js, and TypeScript. I’m integrating the maintenance module with ERP OMIE inventory and contributing to a WhatsApp CRM using WAHA.
I take features from requirements through deployment and ongoing support, and maintain MySQL databases with Prisma ORM. I also configure the GitHub Actions CI/CD pipeline and support teammates with technical decisions and complex issues.
As an independent software developer, I developed and maintained Gastto, a subscription product with web and mobile apps. Its web subscriptions use Stripe, while in-app purchases use RevenueCat and server-side entitlements to control plans and trial periods.
At Liso Perfeito Brasil, I built internal web systems for customer service and equipment maintenance, working across requirements, deployment, and production fixes. Gastto’s apps also use Capacitor, biometric login, Firebase push notifications, and OTA updates.
