Hello, I'm Guilherme.
Fullstack Software Developer
I am passionate about developing high-quality software, focusing on efficiency, user experience, and positive impact.I am a 22-year-old software developer with 4 years of experience, currently living in Brazil. My journey in programming started in high school, driven by curiosity about how the games and software I used at the time were built. I've always enjoyed challenges that require logic and creativity, and as I explored more, I realized that software development was the right path for me.
My focus is on creating high-impact solutions, always prioritizing quality, efficiency, and an excellent user experience. I choose technologies according to the project's needs, without being tied to specific stacks or languages, but my expertise revolves around the JavaScript ecosystem. Additionally, I am an enthusiast of software design and its principles, such as DDD, SOLID, and various architectures.
As a Frontend Developer, I work on implementing new features and improving the architecture of a sales CRM tailored for the automotive sector, used by over 100 dealerships across Brazil. I actively participate in modernizing the system, refactoring legacy AngularJS modules into React, enhancing code maintainability.
Furthermore, I apply SOLID principles and Clean Code, reducing bug occurrences and improving software scalability. I have also developed unit and E2E tests with over 85% coverage, ensuring greater stability in deliveries.
I also collaborate with UX/UI designers and backend developers to transform business requirements into functional and accessible interfaces.
At Wansoft, I worked as a Fullstack Developer, creating and maintaining web software with various characteristics. I was responsible for the complete implementation of an internal HR platform, used daily by over 200 employees.
I developed an agnostic design system for a PSP company dashboard, promoting visual consistency and efficiency throughout the application.
Additionally, I contributed to the implementation of scalable APIs with Node.js, Express, and PostgreSQL, applying Clean Architecture patterns to improve organization and separation of concerns.
