I’m Guilherme Sassi, a Software Engineer passionate about building scalable and user-centered applications. I specialize in mobile and web development using Flutter, Dart, Laravel, and Next.js, applying Clean Architecture and Domain-Driven Design (DDD) to create maintainable, high-performance software.
I enjoy transforming complex ideas into elegant, practical solutions — from mobile apps and B2C platforms to complete admin systems. Currently, I’m part of We Are Dvelopers, contributing to innovative digital products showcased on Shark Tank Brasil.
