Looks like you have JavaScript disabled. For the full Twine experience, you will need to re-enable it.

I'm Renato, a backend-focused software developer with strong full-stack collaboration experience. Over the last year I have architected and built scalable backend systems (APIs, domain models, auth, secure file handling, and real-time sync) using AdonisJS v6 and Lucid ORM, and deploying to Google Cloud Platform (GCP). I enjoy translating complex business rules into maintainable, testable services and creating developer-friendly APIs that integrate cleanly with frontend teams (Nuxt + Vue). In previous roles I partnered with frontend and QA teams to ship robust features and led backend initiatives at Acisum Portugal. I implemented a secure file upload service, designed a central mediatable with polymorphic relationships, and enabled real-time collaboration with Adonis Transmit. I also implemented Google sign-in flows and environment separation for development and production on Google Cloud Platform, while focusing on API design, authorization, file handling, schema design and developer ergonomics in collaboration with Nuxt/Vue frontend.…I'm Renato, a backend-focused software developer with strong full-stack collaboration experience.
