Freelancer profile translated to English.

Description

I am a full-stack web developer specializing in creating modern, fast, and scalable applications that turn ideas into real products. I help companies, startups, and professionals improve their digital presence, optimize processes, and launch technically sound projects with a focus on user experience.

I primarily work with JavaScript, React, TypeScript, Vite, Tailwind CSS, Node.js, and Express, developing clear, accessible, and business-oriented interfaces, along with well-structured and secure REST APIs. I differentiate myself by combining technical vision with a practical approach, prioritizing maintainable code, best practices, and measurable results.

I have developed complete projects from start to finish: professional landing pages, administration panels, dynamic web platforms, booking systems, blogs, e-commerce sites, and applications connected to SQL databases and cloud services. I also have experience in production deployment (Vercel, Railway, Supabase) and version control with Git.

I engage in every project with a product mindset, clear communication, and a solutions-oriented approach, delivering real value beyond just the code.
