I create modern UIs with React.js, Next.js, and Tailwind CSS, and use Material UI, Ant Design, Shadcn, and Framer Motion for polished components and animations.
I use Node.js and Express.js for scalable backend solutions and choose MySQL, MongoDB, or MS SQL based on project needs.
For POS systems, I use React.js for the frontend, Node.js and Express.js for the backend, MySQL for data management, and REST APIs for seamless integration.
