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 London, Ontario. With a deep focus on React.js, Next.js, and TypeScript, I craft fast, accessible, and scalable digital products that bring real value to businesses and their users.

My expertise lies at the intersection of modern front-end development and artificial intelligence. From building AI-powered chatbots and search engines to developing SaaS platforms that streamline complex business operations, I approach every project with a user-centered, performance-focused mindset.

Whether it's translating pixel-perfect Figma designs into production-ready code, integrating OpenAI and Gemini AI APIs for intelligent automation, or architecting serverless solutions on Vercel and Firebase, I bring the technical depth and creative problem-solving needed to deliver outstanding digital experiences.
