I build front-end experiences that don’t just only look good but perform at scale. Over the past few years, I’ve grown from contributing small UI components to collaborating with UI/UX designers and backend engineers on the creation of features that drive the impact of Web applications, SaaS platforms and AI-powered applications. My work sits at the intersection of front-end development and AI integration. I build with React, Next.js, and TypeScript, collaborate in Figma to deliver pixel-perfect UIs, and integrate Supabase, REST APIs, and CMS platforms like Payload or Strapi — independently or with backend teams. By leveraging AI tools such as ChatGPT and Claude to streamline testing, documentation, and workflows, I help deliver scalable, maintainable, and user-friendly solutions that drive real business impact. What drives me is the challenge of turning complex requirements into elegant, production-ready interfaces that users enjoy and companies can scale. I’ve collaborated with distributed teams across 13+ countries and built systems that boosted retention and improved customer experience. I’m always curious, always refining, and always pushing the limits of what front-end development can do , especially as AI becomes an integral part of the craft. 🌍 Open to conversations and better opportunities about building the next generation of front-end solutions.
