Senior Front-End Developer & AI Engineer

Building intelligent, scalable web experiences

I'm Livio Reinoso, a Senior Front-End Developer and AI Software Engineer based in Buenos Aires, Argentina, with a global mindset shaped by collaborating with distributed teams across North America and beyond, with strong experience working alongside professionals in Canada and the United States. I specialize in building fast, accessible, and scalable digital products that create measurable value for businesses and their users.

My expertise sits at the intersection of modern front-end engineering and artificial intelligence. With deep experience in React.js, Next.js, and TypeScript, I build high-performance web applications, AI-powered chatbots, intelligent search experiences, and SaaS platforms that simplify complex operations and improve user engagement.

Whether translating pixel-perfect Figma designs into production-ready code, integrating OpenAI and Gemini APIs for smart automation, or architecting modern cloud solutions with Vercel and Firebase, I bring the technical depth, adaptability, and product thinking required to deliver world-class digital experiences for international teams and markets.
