A RESTful API for managing tasks, built using Spring Boot and MySQL with UUID as the primary key for tasks.
The system allows users to Create, Read, Update, Delete Tasks, and automatically update their status from PENDING to IN_PROGRESS after a specified time using an Asynchronous Scheduler.
SpringBoot Application to Develop a Complete Backend Application for User Login & Registration using Spring Boot including Email Verification Links.
User Login & Registration With Email Verification included Maildev SMTP Server is a project that allows users to create and verify their accounts using email. It uses Spring Boot as the backend framework, and maildev as the SMTP server for sending and receiving emails.
The Event Management System is a Spring Boot application designed to manage and query event data based on a user's Geographical Location and a specified date. It provides RESTful APIs to ingest event data from a CSV file, store it in a database, and retrieve events based on user-specified criteria.
