Web3 Developer | Three.Js

👋 Hi! I'm Cesar, a Web3XR developer exploring the convergence of Web3 and mixed reality (XR) to create more immersive, intuitive, and accessible web experiences. I have nearly 7 years of experience as a full-stack developer, with the last 3 focused on the blockchain space. I've worked with Solana, IOTA, EVM chains like Polygon, and built dApps using React, Next.js, Svelte/SvelteKit, and Node.js. On the back end, I’ve used Express and SQL-based databases to build scalable and reliable systems. Always learning, always shipping. 🚀
