ABOUT ME

Web Developer based in Buenos Aires, Argentina 📍

I'm a Web Developer focused on building fast, scalable, and maintainable web experiences. My professional work centers around Webflow, JavaScript, CMS architecture, performance, and technical SEO, while my projects also span React, TypeScript, backend development, APIs, and workflow automation.

I enjoy working beyond the visual layer of a website, solving problems involving integrations, analytics, automation, and AI-assisted workflows. My background in Business Administration and Accounting also gives me a strong analytical and business-oriented approach to development.
