I’m a results-driven full-stack developer with strong expertise in modern front-end frameworks and backend technologies. I specialize in building elegant, scalable web applications using React, Next.js, Vue, Nuxt, and Tailwind CSS, while delivering robust server-side solutions with Laravel, NestJS, Django, FastAPI and Node.js. My experience includes creating interactive 3D experiences with Three.js and developing decentralized applications powered by Web3 and smart contracts. I enjoy translating complex requirements into clean, efficient code and intuitive user experiences. With a focus on performance, maintainability, and best practices, I help businesses launch high-impact digital products, from responsive websites to blockchain-based platforms, on time and at scale.
