Jumpstart

Project brief

Developed an e-commerce store management system where users can sign-up, after sign in add products to their cart, increase or decrease the quantity and make the payment at checkout. To ensure users can use the site even on smaller screens below 992px screen size, the website had a left category panel and bottom navigation panel, ensuring accessibility with a single hand. The company will receive revenue through razor pay API directly to its bank account. Users can search for products using the search bar and find products brand-wise or category-wise. OTP validation for local email and OAuth sign-in has also been implemented. Users can update their profile information, see their purchasing history, and all the product details they purchased on that order. A contact form associated with webhook slack was also implemented so that users could share their issues with the organization. And all kinds of security issues have been covered to ensure a secure, reliable website. Admin can manage each section of the website from a GUI-based admin panel. To avoid conflict, category, brand, and product id cannot be created with the same name twice. All kinds of alerts have also been implemented to notify users.

ABC Jobs Portal view project

ABC Jobs Portal

Project brief

A user can come and look through all the job openings. If the user wants to apply for a job needs to register first. During the registration, the process user needs to verify their provided email. Users can not provide invalid or try to bypass the OTP validation from the front end. If the appropriate message is displayed, the registration process will stop immediately. User data will be stored in the database only upon providing the correct OTP. Users can log in to the portal but need help with invalid credentials. If so will display the error message accordingly. If the user forgets their password can reset it. Just like registration users need to verify their email addresses first, OTP bypassing is also not allowed. If both passwords are matched only, then the password will change and store in the database—other than will stop the process and displaying an error message. If the password is changed will send a notification email to the user. After login, users can search for others and see their details, find jobs and apply to them, update profile information and password, post threads, and comment on others’ posts. Users can contact the organization through the contact form. Admin can manage everything from GUI-based admin panel from creating an admin to managing (create, delete, update) each website section.

ABC Cars (Spring Boot) view project

ABC Cars

Project brief

A user can come and look through all the cars. Users can sign in and post their car for sales but need to sign up first, and all required backend validation is provided for sign-up and sign-in. Users can contact the organization through the contact us form. Users can update their profile information and password; all required backend validation is provided. During the posting or updating, car for-sales assurances are also offered. Users can make a post inactive or an inactive post active. The sweet alert has been implemented through the website for alerting and getting confirmation. Users can not perform any task if the admin has denied their posts. Users can contact the admin for a banned post to fill out an appeal. To ensure that users cannot perform any task on other users, post-security has been implemented for that as well. Users can see all their bidding with details on the profile page. If not requested, the test drive request button will display; otherwise, it will not display there. Sign-in is required to see and perform bidding. Bidding is only possible if the user does not hide the car, is denied by the admin, or is not transacted (sold). The same goes for the test drive also. Appropriate error or success messages will be invoked for all kinds of circumstances. Requesting a test drive is possible only once, but users can re-bid multiple times until the transaction is made. To ask for the test drive, the user must bid first. Only for admin the admin access link will show on the profile page. From there can maintain and manage each section of the website, posting, editing, changing roles, transacting cars, seeing user or post details, accepting/rejecting, pending user post or test drive requests, and responding to the user’s queries.

Hacking Website view project

Hacking Website

Project brief

Developed a hacking website. A weather report web application where users can visit and get the weather report according to their location. They can also search for other places and see the details. Once A user is looking for a weather report, within 3 seconds, her details will capture and send to the server excel file (for testing purposes, it is Google Workplace Sheet instead of the actual server). Develop for fun purposes. But this kind of app has a sense of being used in the real world.

If a user doesn’t allow the location, even the IP address and User Agent will fetch, and everything can be found.

The app can be modified so parents can use it; once a parent wants to know their child’s location, the website will share that.

The app also can be used for safety purposes. Once clicked, anyone in danger can share their location with their family members and law enforcement. Thus, finding a person can be more accessible.
