Hi, I'm Mohammad Mahdi Sanjari, a Front-End Developer with over five years of experience crafting scalable and user-friendly web applications. I specialize in React and TypeScript, and I have a passion for building performance-optimized front ends that are also visually appealing. Alongside front-end development, I contribute to back-end systems using Django and FastAPI, which gives me a well-rounded perspective on web development. I've worked on a variety of exciting projects, particularly in crypto-wallet security, AI-powered tools, and Web3 interfaces. I enjoy collaborating with cross-functional teams remotely, and I am always eager to learn and optimize code for better performance and maintainability. I believe clean, scalable code is the foundation of any great product.
