About Vitor

Full-stack developer specializing in Ruby on Rails, Next.js, React, and TypeScript, I help startups, SMEs, and companies design and develop modern web applications, business tools, and SaaS platforms.

I work on the entire development cycle: API creation, third-party service integration, process automation, AI-based features, high-performance dashboards, and user interfaces.

I have developed several applications in production and also contribute to open-source projects like Kaminari and ruby-openai. I also use Docker, GitHub Actions (CI/CD), and AI tools daily to accelerate development while maintaining a high level of quality.

Pragmatic and results-oriented, I prioritize maintainable code, clear communication, and rapid deliveries to create value from the first iterations.
