Hello, I'm
Lina Villalba.
Full-Stack Developer | Freelance
Passionate about building scalable digital solutions that solve real problems. With 3+ years of experience, I transform ideas into high-impact web products, focusing on clean code, performance, and user-centric design.

About me
I'm Lina, a freelance developer with end-to-end experience in building digital products—from crafting user interfaces to implementing APIs and deploying to production. I’ve worked on various projects handling both frontend and backend development, leading complete development cycles with a focus on quality, scalability, and user experience.
While I'm especially passionate about frontend development and creating user-centered experiences, I'm also confident working on the backend. I've built APIs, configured servers, managed databases, and deployed applications using tools like Nginx. My backend experience includes both Node.js/Express and Java Spring Boot, which allows me to adapt to different architectures and project needs. This versatility has enabled me to work independently on full product builds as well as integrate seamlessly into team environments.
My main tech stack includes React, Next.js, Node.js, Express, and Spring Boot, but I'm always learning and adapting to each project's requirements. As a freelancer, I've developed strong problem-solving skills and the ability to make strategic technical decisions. In team environments, I follow best practices in collaboration, version control, and agile methodologies.
Currently, I focus on building solid, accessible, and high-impact digital solutions while continuing to grow as a fullstack developer, exploring new technologies, and creating products that deliver real-world value.
