About Samuel

💻 Full Stack Developer with React, Next.js, and TypeScript.
I build fast, accessible, and intuitive web interfaces, paying attention to visual detail, performance, and user experience.

I also handle backend with Node.js, Express.js, and SQL, which allows me to design complete solutions and collaborate smoothly with APIs, endpoints, and server-side architecture when needed.

I have worked on long-term projects, improving performance, reusable components, and visual consistency, as well as collaborating with multidisciplinary teams to ensure quality and reliable deliveries.

☕ Outside of code: cats, plants, coffee, music, design, and sports. I am curious, self-taught, and passionate about technology.
