Taskify

Taskify is a task management application built using Node.js, Express, MongoDB, and Mongoose for the backend. The frontend is developed by using Angular (v19). This project was primarily a training exercise focused on backend development, with greater emphasis on implementing and refining server-side functionality than on frontend development.
