This document contains the problem statements and proposed solutions for three full-stack web applications.
In the modern digital era, online fraud and scam activities are increasing rapidly. People frequently receive fraudulent phone calls, phishing links, fake job offers, and misleading messages asking for sensitive information such as OTPs, bank details, or payments through UPI. Many individuals fall victim to these scams because they do not have a reliable and quick way to verify whether a phone number, website, or payment ID has already been reported as fraudulent by others.
Although cybercrime awareness is growing, there is still no widely accessible platform where users can instantly check suspicious contacts before interacting with them. As a result, scammers continue to target individuals, causing financial loss and compromising personal data.
Therefore, there is a need for a centralized and community-driven system that allows users to verify suspicious entities and report new scams, helping others avoid similar threats.
ScamShield is a community-driven web platform where users can search suspicious phone numbers, URLs, or UPI IDs to check whether they have been reported as scams. Users can also report new scam activities, creating a shared database that helps spread awareness and prevent digital fraud.
People often have thoughts, messages, reminders, or motivational notes that they would like to send to their future selves or others at a specific time. For example, someone might want to write a motivational message for their future self, schedule a birthday message for a friend, or store a meaningful memory to revisit years later.
However, there is no simple and accessible platform that allows users to write a message today and securely store it until a specific future date. Most messaging platforms focus only on real-time communication and do not support long-term message scheduling or time-locked digital memories.
Because of this limitation, people miss opportunities to preserve their thoughts and deliver meaningful messages in the future.
Future Message Locker is a web application that allows users to compose messages and schedule them to be unlocked or delivered at a specific future date and time. The platform acts as a digital time capsule where users can securely store memories, reminders, and personal messages for the future.
In many public service environments such as hospitals, banks, government offices, and service centers, people often spend long periods waiting in physical queues. These queues can become overcrowded, leading to frustration, wasted time, and poor service experience.
People are often forced to stand in line without knowing how long they will need to wait. This lack of transparency creates inconvenience for users and makes service management difficult for organizations.
Additionally, physical queues can lead to inefficient crowd management and unnecessary congestion in public places.
Therefore, there is a need for a digital system that can manage queues more efficiently and allow users to monitor their waiting time without being physically present.
QueueLess is a digital queue management platform that allows users to take tokens online and track their position in the queue in real time. The system provides estimated waiting times and notifications when a user's turn is approaching, helping reduce crowding and improving overall service efficiency.
