Contest-Saathi

Users often missed contest deadlines, so I built Contest-Saathi, a web application that sends personalized email notifications and real-time updates. This solution, using Nodemailer, now serves over 50 active subscribers, ensuring they receive prompt reminders and never miss a contest.
