This thesis explores the development of an e-commerce platform dedicated to handmade clothing. This is driven by my desire to support my mother's clothing business. Various technologies are used like TypeScript, Next.js, MongoDB, Vercel, Firebase Cloud Storage, Prisma ORM, and NextAuth. One of the features of the platform is its simple and intuitive user interface, designed to enhance user experience. The project still offers room for future enhancements and refinements, and I will continue its development.
